Running commands across the environment

Posted on February 7, 2014

The daily maintenance across a small environments can be an easy job, but when our environment grows to a point where we have several appliances it can be a though job. For example, in case we need to monitor the Disk Space in a environment of just one appliance, we can simple connect through SSH to the QRadar and run a Linux command such as ‘df -h‘, but in a large environment with several appliances this practice would take a lot of time.

In the QRadar distributed environments, the console acts like a central management console to all the another appliances. In our example of monitoring disk, wouldn’t be easier if we could run a command in the main console to get information about all the environment? It’s exactly what the script ‘all_servers.sh‘ does. The script is located at:
/opt/qradar/support/all_servers.sh

To run the command, you can use the following syntax:
[root@MY_RADAR]# ./opt/qradar/support/all_servers.sh ‘COMMAND’
(Where COMMAND is what you want to run in the appliances)

In our example of monitoring the disk size, we could use:
[root@MY_RADAR]# ./opt/qradar/support/all_servers.sh ‘df -h’ > /root/drive_space.txt
And it would write the result of the script on all the servers in the following file: /root/drive_space.txt

The script can be used for several different purposes: Monitoring disk space, Monitoring CPU, Viewing network configurations, checking logs, etc. Can you imagine how it could help in your environment?! Had good ideas of how to integrate it with your monitoring systems?! Let us know in the comments!
