HP Insight Control Software for Linux - Manual (Page 225)

These messages can occur if metrics collection cannot be completed in a reasonable time; examine the
/opt/hptc/nagios/etc/nagios.cfg
file for the value of the service_check_timeout
parameter.
The default works best for configurations with fewer than 256 managed systems.
Increase the value of the service_check_timeout parameter to solve the problem for configurations
with more managed systems.
Also, run the following command to verify that the supermond service is running on the CMS:
# /etc/init.d/supermond status
Loss or time-outs of this service can cause per-managed system warnings for nodeinfo, load average
and system free space.
A non-timeout warning or critical message indicates some monitored managed systems are not
responding; this is normal if the managed systems are down or otherwise disabled.
Service: Syslog Alert Monitor
Status Information: Status of consolidated.log syslog monitoring
Reports the number of new records processed in the /hptc_cluster/adm/logs/consolidated.log
file.
A warning or critical message occurs when there is insufficient time to process a huge volume of messages
before the Nagios service_check_timeout period expires.
Nagios examines the recent incoming consolidated log messages and issues a warning or critical
message if the incoming rate since last interval exceeds a configured number of records. The default
values are 2 for warnings and 20 for critical. See /opt/hptc/nagios/libexec/
check_syslogalerts
for details.
No specific action is required unless the service times out. In that case, an excessive number of syslog
messages is collected across the system; this is more than the plug-in can process in the
service_check_timeout
period. See the /opt/hptc/nagios/etc/nagios.cfg file for the
value of the service_check_timeout parameter.
To solve the problem, run the following command on the system reporting the error:
# /opt/hptc/nagios/libexec/check_syslogalerts –domain node:nagios_monitor –nsca
Otherwise, wait for the nightly log to roll over.
Service: Syslog Alerts
Status Information: Node Syslog alerts information
Reports the number of alerts in a specified period of time and allows you to access the most recent log.
A warning or critical message indicates that one or more rules defined in the /opt/hptc/nagios/
etc/syslogAlertRules
file matches the specified system's consolidated log file.
Take the appropriate action based on the message.
Service: System Event Log
Status Information: Node Syslog alerts information
A warning or critical message indicates that one or more rules defined in the /opt/hptc/nagios/
etc/selRules
file matches the specified system's firmware System Event Log.
Take the appropriate action based on the System Event Log message.
Service: System Free Space
Status Information: Node / and /var free space
This entry typically displays the status of the /, /var, and /hptc_cluster file systems on the system.
A warning or critical message indicates that the thresholds for the specific managed system were
exceeded.
Clean up disk space.
25.14.6 A check_nrpe error occurs during management agents installation
