23.13 Troubleshooting monitoring problems
The following table describes possible causes of problems related to monitoring and provides
actions to correct them. Problems related to the Performance Dashboard tool are described in a
subsequent table.
Corrective ActionsCause/Symptom
Ensure that the Configure→Configure or Repair Agents
task was run on the managed systems.
Cannot distribute pdsh keys
Ensure that the management hubs were installed with
Management-Hub.cfg or have all required Linux RPMs
installed.
Failure trying to install monitoring RPMs
Ensure that nrpe is running on the managed systems:
# /etc/init.d nrpe status
check_nrpe error: Connection refused by host
Use the /sbin/csys command to examine the
/hptc_cluster cluster export status:
# sbin/csys status
/hptc_cluster local, exported
# /sbin/csys umount /hptc_cluster
# cat /etc/exports
.
.
/hptc_cluster
192.118.192.143/255.255.240.0(rw,no_root_squash,sync)
Problems exporting /hptc_cluster across the management
hubs
Perform the appropriate action:
• Ensure that the
/opt/hptc/syslog-ng/bin/syslog-ng command
is running on the management hubs:
# /etc/init.d/syslog-ng status
• Run the logger command to verify that syslog
messages appear in the consolidated log and in the
aggregated log files:
# pdsh –a logger –p warn "test msg1"
# grep "msg1" \
/hptc_cluster/adm/logs/consolidated.log
Syslog events for managed systems are not showing up
in consolidated log
Verify the cause of the problem by performing the
following actions:
1. Log in to managed system as the root user.
2. Manually run the /opt/hptc/mgmt/bin/
install.sh script to view the wget failure.
The wget command fails:
• If there is a proxy server in your environment that is
not configured properly
• If the appropriate network ports open on the managed
system are not open. For more information, see
“Opening network ports on managed systems”
(page 48)
Take the corrective action based on the wget failure.
Configure→IC-Linux→Configure Management
Services fails with wget error on managed system so
HP Insight Control for Linux management agents cannot
be installed on the managed system.
