PostgreSQL pgBadger

pgBadger is a PostgreSQL log analyzer built for speed with fully reports from your PostgreSQL log file. It's a single and small Perl script that outperforms any other PostgreSQL log analyzer.It is written in pure Perl and uses a JavaScript library (flotr2) to draw graphs so that you don't need to install any additional Perl modules or other packages. Furthermore, this library gives us more features such as zooming. pgBadger also uses the Bootstrap JavaScript library and the FontAwesome webfont for better design. Everything is embedded.pgBadger is able to autodetect your log file format (syslog, stderr or csvlog). It is designed to parse huge log files as well as gzip compressed files. See a complete list of features below. Supported compressed format are gzip, bzip2 and xz. For the xz format you must have an xz version upper than 5.05 that supports the --robot option.All charts are zoomable and can be saved as PNG images.You can also limit pgBadger to only report errors or rem…

PgBadger is a tool that analyzes PostgreSQL log files and generates reports on execution of SQL and server operation. Statistical reports analyzed from a number of perspectives can be useful not only for grasping the usual database operation but also as a hint for performance improvement.

The report output by pgBadger has the following features. Graph output in HTML format Many statistical objects Daily, Weekly unit creation possible 1.Graph output in HTML format
Many of the analysis results can be displayed in graph form by outputting the report in HTML format (output in text format or JSON format is also possible). By analyzing the log information graphed, it is much more prospective for people to see than the raw log data. So, if you do not need to handle it with another tool separately, we recommend report output in HTML format.

2.Many statistical objects A lot of data useful for database performance analysis is output in the report as shown below. Queries (total number of executions, maxi…

How To Schedule PostgreSQL Jobs using pgAgent on Linux plateform

Taking regular SQL database backup is one of the most important responsibilities of a database administrator. By setting up automatic database backup we can get rid of the additional overhead of doing it manually, every day, week or month. When it comes to PostgreSQL running in any Unix distributions or in Windows, there are at least two ways to do it. Using the built in CronJobs/ CronTabs in case of  Linux, and Windows scheduled tasks in Windows .Using PostgreSQL’s own scheduling agent, pgAgent.Often DBAs tends to rely on CronTabs or Scheduled tasked because of the ease of use it offers. But there are several advantages if you use pgAgent instead. Though it takes a little effort to install pgAgent, it is much better than Cron jobs or Scheduled tasks.
Why use pgAgent over CronJob:Compared to CronTab, PgAgent has the following advantages: 

You can have multiple steps for a job without having to resort to a batch script.You can have multiple schedules for a job without having to repeat the…

The current `repmgr` version (3.3) supports all PostgreSQL versions from 9.3 to 9.6. Overview The repmgr suite provides two main tools:1.repmgr - a command-line tool used to perform administrative tasks such as: - setting up standby servers - promoting a standby server to master - switching over master and standby servers - displaying the status of servers in the replication cluster 2.repmgrd is a daemon which actively monitors servers in a replication cluster and performs the following tasks: - monitoring and recording replication performance - performing failover by detecting failure of the master and promoting the most suitabl…
