Check the sensor status on the enclosure. Verify the status of the
Enclosures Collection Monitor which provides this data.
nh <Enclosures Collection Monitor - Critical> The Enclosure Collection
Monitor collects sensor information from the blade system enclosures.
Enclosure status can be found in the Nagios Enclosure Status service
plug-in status. A critical status indicates that one or more of the
monitored enclosures has either posted a critical status or the
plug-in has been unable to contact the enclosure. Verify logon
credentials are correct if sensor data is not available.
mercury nh neptune <Load Average - Critical> Nodes have crossed the load average warning
thresholds set in nagios_vars.ini. These are site specific values and
simply indicate resource usage above an expected range. Verify that the
node does not have a misbehaving job or some other problem causing it to
use more CPU then expected.
mercury neptune NodeInfo - Critical> Critical thresholds have been reached for max users,
processes, or zombies etc. See nagios_vars.ini for threshold values.
Values are site specific and critical values indicate values have been
exceeded.
The nrg command can generate the following information:
•
A list of systems according to their severity, as follows:
Critical ◦
◦ Warning
◦ Ok
◦ Unknown
◦ Pending
•
Nagios hosts status
•
Nagios services status
•
Nagios monitors status
•
A list of systems that are up or down
For more information, see nrg(8) and use the --help option to display valid command options.
For example,
# nrg --help
--help

c - critical, w - warning, o - ok,
u - unknown, p - pending
--hosts - Only list hosts status
--services - Only list service status
--monitors - Only list monitor status
--up - Only up nodes
--down - Only down nodes
--sort t,h,s - Sort by (t)ime, (h)ost, (s)ervice
--sort <c,w,o,u,p> - Summary mode only (as cwoup as in severity)
--mode - Report mode: (f)ull, (s)ummary, (r)aw, (w)atch, (a)nalyze
