SysEDGE on multiple servers stopped working suddenly, and are not responding to SNMP requests.
Restarting SystemEDGE the agent hangs and is not initializing properly.
SystemEDGE agents run independently.
If multiple SystemEDGE agents are impacted simultaneously the problem is cause by an environmental issue.
After restarting the SystemEDGE agent the last entry in the sysedge.log is:
add_monitor_entry(): Self monitor index 1000005 configured with variable OID 188.8.131.52.4.1.5184.108.40.206.4.1 which is not yet available.
diskStatsUtilization -> diskStatsEntry.4 (220.127.116.11.4.1.518.104.22.168.4)
Type: INTEGER Access: read-only
The utilization rate (percentage utilization) for this disk over the last measurement period. This could also be expressed as (disk busy time / elapsed time) * 100.
Disabling SystemEDGE Disk Based polling within the sysedge.cf file allows SystemEDGE to fully initialize:
Running df -h command also hangs.
A non responsive File System\Disk Array Issue is causing SytemEDGE to become unresponsive.
SystemEDGE is a single threaded application and something like a hung\stale NFS mount can cause a "blocking call".
