---------------------------------------------------------------------------------------
Key: HHQ-5878
URL: https://jira.hyperic.com/browse/HHQ-5878
Project: Hyperic HQ
Issue Type: Bug
Components: Agent / PDK
Environment: Redhat 6.1
Reporter: Tal Goldman
Assignee: Tal Goldman
Priority: Minor
Fix For: 5.8
>
Hyperic agent script cannot start if COLUMNS environment variable is set in UNIX enviroment.
When we issue the following command:
$/xxx/agent-5.0.0-EE/bin/hq-agent.sh start
The following was printed:
Starting HQ Agent......Removed stale pid file:
/local/install/cfgsas1/config/Lev1/Web/SASEnvironmentManager/agent-5.0.0-EE/wrap
per/sbin/../../wrapper/hq-agent.pid
WARNING: HQ Agent may have failed to start.
Our team concluded that the COLUMNS environment variable was set and was causing the agent start script to misread the agent pid file. When the agent script greps the output of the ps command for sbin/wrapper it does not find it.
because ps is honoring his COLUMNS environment variable. When COLUMNS is not set, everything works as expected. The fix is fairly simple - unset COLUMNS before running ps, in the getpid() functions in the script(s). This should be done in the shell versions of the script:
getpid() {
pid=""
+ unset COLUMNS
if [ -f "$PIDFILE" ]
then
if [ -r "$PIDFILE" ]
Another solution is to add 'ww' to the ps args when executed.
