Different types of MongoDB monitoring tools

February 1st, 2013 No comments

MongoDB monitoring service makes it easier for the users to have the ability to monitor their MongoDB clusters popularly known as MMS’. This is an online web interface, which enables you to access the custom dashboards, charts and constitutes the automated alerting options since it uses the clouds technology to get to the servers. These tools do not require minimum updates, setting, and configuration from the user and partly work alone in the monitoring process. Once you have developed this system, it becomes easier to start the administration in the management, deployment, and optimization of MongoDB.

Starting the set up

In order to activate the MongoDB monitoring service, you need to ensure that you have all the details of the Mongo DB community and they include

Opening an account with the software system

Start the download process of the MMS and install the agent on the cluster as directed by the program

In a matter of munities after he update, you will find the data visible and easy to start the process of monitoring.

Different MongoDB monitoring tools

There are various MongoDB monitoring tools monitoring tools and you need to understand the compete process of installing and updating them into the system and this makes it easy to start using it.

  • Mongostat- this is one of the vital utility programs, which exposes the MongoDB metrics, and it is a good way to start the analysis, and sort any issues when it comes to matters of performance.
  • Mongotop- this is a good way of monitoring the system and it has good and easy to customize tools listed on the page.
  • Query profiler- this is a database profiler used to analyze all the slow queries, and you get to a snapshot of all the details happening on the page.

Http Console- this tool allows the process of simple diagnostics on the screen

  • Mango shell commands- this gives the stats on the current database one is viewing. However it takes a longer time to run and can block other operations in the process.

Trending/ monitoring adaptors- this comprises a set of different monitoring and command tools, which include

  • Munin- this retrieves the details from the server stats, and the collection stats displays collection in form of index sizes and needs the python and driver to connect.
  • Motop- this is a tool used for monitoring various multiple MongoDB severs and it becomes easier to make all the settings since it has the ability to offer updates and conduct monitoring by the minute.

Other MongoDB monitoring tools

  • Dex is one of the cores Mongo DB monitoring tools and this analyzes those who have logged into the system. This offers a number of different examples of indexes and this helps you to gain relevant results when you initiate the monitoring process.
  • Hosted monitoring- this involves different monitoring services which include the cloudclick, server destiny, and scouts app, slow queries.

When you want to launch different MongoDB monitoring tools, it is important you understand all the functions and the command tools you will use to initiate the monitoring options.

MongoDB advantages and disadvantages

January 27th, 2013 No comments

MongoDB is one of the greatest SQL free database, in the market. There have been different variations and introduction in java and programming but this is one of the best developments in the market. Most of the programmers find it easier to adjust to it since the infrastructure accommodates working abilities with other modes in the market. It enables high scalability, performance, and an open source of document database.

With all the monitoring tools, you will find that it becomes easier to let the program run, and all the servers have the ability to adjust and make necessary updates once issued the commands. All the monitoring and command tools have the effective functioning handles making it easier to control and this means that you do not need to employ people to keep on upgrading or monitoring the system due to the presence of tools that can perfectly handle these functions.

Due to the c ++ language, it becomes easier to deal with emergency issues due to the various database applications but this responds instantly to emergency ,making the system to run on smoothly. With the backup database, you only need to add and remove details on the serve based on your need. It is advisable for one to settle with most of the backup devices but the MongoDB makes it applicable to run multiple servers, and monitor, update them at the same time.

The sharding aspect makes it possible to update servers even when you do not have space by duplicating the space and has different memory storage areas. This enables accommodation of data up to double the current amount you have. This is good for the systems that have various online clients like online gaming and big companies that have loads of data that the clients have to visit online. This makes it easier to hold information and disseminate upon request.

There is the use of multiple document transactions since the program is document oriented and become easier to share. This means that one document used by numerous of people at the same time with no delays.

The program is horizontally scalable meaning it has schema-less databases. This is one of the important aspects in the programs and when compared to the other versions, you find that this is due to effectiveness and ability to use joins for queries.

When you have installed the MongoDB, you have higher chances of securing your data due to the duplication of content, which makes it easier to store in RAM, cloud technology amongst other areas, which enhance the accessibility, and easy to adjust the changes.

However, the MongoDB programming does not offer all the solutions that users want and one of them is higher chances of losing data when you are adapting the content, and hard to retrieve it. This is the reason why you need to be sure of the clients you want to update or database duplication failure to which you have higher chances of never getting back the data. Most of the trained personnel using this system prefer using the replica methods in order to have backup content when doing any form of adjustments to the system.

3 Things You Must Know To Get Started With Wireless Internet Service

January 23rd, 2013 No comments

It is one thing to take a decision that you will switch from your conventional home cable connection
and Wi-Fi setup to the more advanced mobile internet connectivity and it’s a complete different thing
to actually get started using this new technology from scratch. This is why it is recommended that you
have a clear idea about the starting blocks of the mobile internet connectivity technology and ensure
that you seek help from your service provider at the sign of any problem.

Here are the top and most important 3 things about starting off using a mobile wireless internet
connectivity that you need to know in order to make your experience of transition a hassle-free one –

1. Getting Connected

When you have subscribed to a plan with the service provider of wireless mobile internet
connectivity of your choice, you will most probably be having the necessary device and
login credentials with you. In case you don’t have it, then you need not worry. Your service
provider will call you up with a convenient time for you to setup the connection once your
order has been processed and approved.

Remember to check with the service provider about any terms of usage that might be there
for the device for the mobile internet connectivity. Also check to see that all necessary
documentations of the device and the driver media are provided with the device. Many
service providers will also provide a wireless Wi-Fi router for your device in order to enable
you to get the internet connection on multiple devices simultaneously.

2. The Devices For The Connection

Once you have the necessary devices you will need to install the same with the computer.
Connect the device and wait for the computer to recognize the same. Once it has recognized
the device, it will ask for the driver media which you will need to insert for installation of the
driver and the service provider’s software. Once done with these, you are all set to go.

There are various ways in which you can pay for your device, both the USB dongle come
antenna for connecting to the internet and the Wi-Fi router that your service provider provides
along with the package. You might need to pay an initial one time refundable security deposit
for these devices or you might be required to purchase the same from the service provider or
buy your own from a shop. Some service providers like clear internet promotions offer the
device free of any additional cost.

3. Range And Security Of The Devices

Remember that any form of wireless or Wi-Fi device, no matter how strong it is comes with
a range beyond which it will be unable to transmit any data and provide internet connectivity.
You will need to ensure that you take care of this aspect of the router when setting it up in
your home. Also ensure that you have a secure password protecting your internet connection
from unauthorized intrusion.

With these 3 aspects of the getting started of wireless mobile internet connectivity taken care of, you
can rest assured of a good time!

5 Ways You Can Protect Yourself from Online Threats

January 22nd, 2013 1 comment

In a world where everything is connected online, it is very easy to lose the files on your
computer or even your own identity. Protecting yourself from the threats in the virtual world is
one of the primary concerns.

There are scams being hatched to hoodwink people into disclosing their personal details and
account numbers and the security breach is too advanced to control. Do worry too much because
there are experts who can guide you through these problems. Given below are five ways in
which you can protect yourself from these online threats.

1. Install Software For Internet Security

It is no longer sufficient to install only antivirus software in your computer or laptop. Use
software that not only prevents your computer from virus threat but also protects you from
spyware and key loggers. The software should also be able to monitor if your computer is being
accessed by any unauthorized person.

Some softwares, which work as both antivirus and protect your computer, may be a little
expensive. But they are worth it. If you do not want something expensive, you can also find
some free software on the net that you can download.

2. Install A Firewall

A firewall acts like buffer zone between your computer and the whole internet. It is created in
a manner that it allows only that information that you allow to pass through it. This is a great
safety device for your computer, as its programming helps you stop the attack from key loggers,
malicious hackers and worms. You can get lot of internet security software that also has a

3. Scan Your Computer Every Week

There are several applications that automatically check the computer for any potential threats. If
your software doesn’t carry out automatic checks then you should scan your computer at least
one every week. It may be a hassle when you are working on the computer, so you may do this
when you are not working. This is important to check that your computer and all the data you
store in it are safe.

4. Update All Your Software Regularly

The hackers and people who are phishing are regularly updating their moves, so it is important
that you keep your internet security software updated as well. You do not have to buy an updated
version from the market, most companies allow you to download the latest version from their website once you have bought the product from them.

5. Keep Back Up For All Your Files

You have your whole life on your computer and when your computer falls prey to a virus or is
hacked, you are completely at loss. To avoid this, you should make a smart move and use any
reputed online backup service for your files and documents. There are various services online,
which are trustworthy and you can make full use of them.

Follow these safety measures and be wary when interacting with unknown people on the

In order for one to get appealing results, they have higher chances of getting positive results in terms of using the best options that enable one to settle with affirmative and timely operational methods

There are different factors that promote backup frequency and they include

The rate of transaction rate

Availability of database

The value of the data company








databases in ARCHIVELOG mode:

log_archive_start         = TRUE

log_archive_dest_1        = ‘LOCATION=/arch_dir_name’

log_archive_dest_state_1  = ENABLE

log_archive_format        = %d_%t_%s.arc


difference between restoring and recovering?

SQL> connect SYS as SYSDBA



RMAN> run {

set until time to_date(’04-Aug-2004 00:00:00′, ‘DD-MON-YYYY HH24:MI:SS’);

  restore database;

  recover database;

online database backups?


! cp xyzFile1 /backupDir/


ALTER SYSTEM SWITCH LOGFILE;   — Force log switch to update control file headers


RMAN can be operated from Oracle Enterprise Manager, or from command line. Here are the command line arguments:


Argument     Value          Description


target       quoted-string  connect-string for target database

catalog      quoted-string  connect-string for recovery catalog

nocatalog    none           if specified, then no recovery catalog

cmdfile      quoted-string  name of input command file

log          quoted-string  name of output message log file

trace        quoted-string  name of output debugging message log file

append       none           if specified, log is opened in append mode

debug        optional-args  activate debugging

msgno        none           show RMAN-nnnn prefix for all messages

send         quoted-string  send a command to the media manager

Backup methods and tools for MySQL

January 18th, 2013 1 comment

MySQL needs to have different backup recovery system, which will prevent loss of files generated into the system. This mostly happens during upgrading of systems or integration of different networks.

Causes of crashes

There are different causes that lead crashing of the system and this makes it harder for one to recover. With a number of different solutions to use, it is wise to understand the methods that cause hitches and try different ways to prevent. Some of the common causes include

Crashing of the operation system

Abrupt and constant power failure

Crashing of the file system

Where there are issues with hardware, motherboard, or hard drive

These are the possible areas ,that lead to constant crashing of the system and this means all data stored have higher chances of getting lost but there are different methods one can use to restore the files.

How to manage using a file snapshot system

It is important for the programmer to take into account different methods that make it easier for one to get the data files in the system. This systematic process needs attention to detail in order to get recommendable results.

–  create a client program, and execute FLUSH TABLES WITH READ LOCK.

– create another shell, execute mount vxfs snapshot

–    choose first client, execute UNLOCK TABLES.

–    Copy files from the snapshot

–    Unmount the snapshot.


Tools used in the backup and recovery process

ZRM with XtraBackup (and streaming)


MySQL backup methods and characteristics

Backup uses querying the MySQL server to get database construction and gratified information

Backup is gentler than physical approaches because the server should access database material and adapt it to logical format. If the production is written on the client side, the server must also send it to the holdup program.

Output is particularly bigger than physical backup, predominantly when saved in text setup

Backup and reinstate granularity is obtainable at the server level), database level (all tables in a, or table level. this happens regardless of the type of server of backup device.

The backup should not compose log or configuration files, or database-related files that are not part of databases.

Backup methods and tools for PostgresQL

January 17th, 2013 No comments

There are different methods that one can use in order to backup and restore files.

Using pgdump, new file for each day


Go to Server create a Directory called Drive:\PostgresqlBack then create a sub directory called “bin” in the Drive:\PostgresqlBack















Create batch file called something, example is postgresqlBackup.bat. The file must be located in PostgresqlBack directory not the bin folder.


Open the File then Copy/Paste the following


@echo off

for /f “tokens=1-4 delims=/ ” %%i in (“%date%”) do (

set dow=%%i

set month=%%j

set day=%%k

set year=%%l


set datestr=%month%_%day%_%year%

echo datestr is %datestr%

set BACKUP_FILE=<NameOfTheFile>_%datestr%.backup

echo backup file name is %BACKUP_FILE%


echo on

bin\pg_dump -i -h <HostName> -p 5432 -U <UserName> -F c -b -v -f %BACKUP_FILE% <DATABASENAME>

Change <NameOfTheFile> to something. Setting is the first part of the file name then followed by the date the file was created with the extension .backup

Change the <PassWord > setting above to the correct password for the backup users.

Change <HostName> either to ip address or dns name of the server hosting Postgresql.

Change <UserName> to backup user make sure this users has access to database for backup purposes

Change <DATABASENAME> to the database name being backed up.

Save the File

Create Task for the MS Task Scheduler

Using .pgpass and pgdumpall, same file

Achieving automated backup in a windows environment


Create a .pgpass file

Lock down the .pgpass file

Using NTFS permissions, disable access to this file for everybody except the user pg is running as

Create a script to call pg_dumpall


“C:\Program Files\PostgreSQL\8.2\bin\pg_dumpall.exe” -U scfcu_postgres > C:\foo\bar\PG_BACKUP\db.out cu

Handling Large Databases

Use compressed dumps. You can use your favorite compression program, for example gzip:

pg_dump dbname | gzip > filename.gz

Reload with:

gunzip -c filename.gz | psql dbname


cat filename.gz | gunzip | psql dbname

Use split. pg_dump dbname | split -b 1m – filename

Reload with: cat filename* | psql dbname

You can use PostgreSQL’s continuous WAL archiving method. First you need to set wal_level=archive, then do a full filesystem-level backup (between issuing pg_start_backup() and pg_stop_backup() commands) and then just copy over newer WAL files by configuring the archive_command option.


Update: Check out Barman for an easier way to set up WAL archiving for backup.

Incremental, the WAL archives include everything necessary to restore the current state of the database

Almost no overhead, copying WAL files is cheap

You can restore the database at any point in time (this feature is called PITR, or point-in-time recovery)


More complicated to set up than pg_dump

The full backup will be much larger than a pg_dump because all internal table structures and indexes are included

Doesn’t work work well for write-heavy databases, since recovery will take a long time.
