Unix/Linux Offline Agent Deployment
You can install the Agent in offline mode. The Agent is installed but not registered. An ITM On-Prem (ObserveIT) service is responsible for checking the Application server periodically.
Deploying the Agent in Offline Mode
ITM On-Prem (ObserveIT) Application Server must be unavailable when you execute the script.
To execute, run the command:
./observeit-agent-RHEL6-7.9.0.79.run -- -i -s 10.2.8.15 -m
Once you deploy the Agent in offline mode, only one ITM On-Prem (ObserveIT) service will be running.
For example:
c65-64-1:~$ ps -ef |grep obitd
root 1589 1 99 18:27 ? 00:01:01 /usr/sbin/obitd
userfolder 1898 1855 0 18:28 pts/0 00:00:00 grep obitd
c65-64-1:~$ sudo oitcheck
Detected platform: Linux - "CentOS release 6.5 (Final)"
Check for oit package: PASS
oit-7.9.0.79-1.x86_64
Check for obitd service: PASS
STATUS: obitd (pid 1589 )is running...
Check that obitd daemon running: PASS
Check for /opt/observeit/agent/run directory: PASS
Check for /opt/observeit/agent/conf/obit.conf: Not PASS
Checking for registration by remote app server: ERROR
Checking for Obit basic interception linkage: Not PASS
Checking SELinux status:
STATUS: disabled
When script is finished make sure:
-
Configuration file "obit.conf "does not exist
Check for /opt/observeit/agent/conf/obit.conf: Not PASS -
Registration returns an error
Checking for registration by remote app server: ERROR -
Interception does pass
Checking for Obit basic interception linkage: Not PASS
Preparing Golden Image
If you want to prepare a golden image, you must complete the deployment offline (Deploying the Agent in Offline Mode).
Then you can shutdown and prepare your golden image. The Agent will register itself when the Application server is available.
To check an installed Agent's registration and health status, run the command:
/opt/observeit/agent/bin/oitcheck
For example:
c65-64-1:~$ sudo oitcheck
The results should look like this (on a CentOS Linux-based supported platform):
Detected platform: Linux - "CentOS release 6.5 (Final)"
Check for oit package: PASS
oit-7.9.0.79-1.x86_64
Check for obitd service: PASS
STATUS: obitd (pid 2132 2153 2156 2159) is running...
Check that obitd daemon running: PASS
Check for /opt/observeit/agent/run directory: PASS
Check for /opt/observeit/agent/conf/obit.conf: PASS
HostURL: http://10.3.0.68:4884/ObserveITapplicationServer
WebConsoleURL: http://10.3.0.68:4884/ObserveIT
Checking for registration by remote app server: PASS
Checking for Obit basic interception linkage: PASS
Checking SELinux status:
STATUS: disabled (edited)
Open a new SSH session and check the web console to verify that the Agent is working.
