Monitoring cluster health
To monitor the functional health of file serving nodes and StoreAll clients, execute the
ibrix_health command. This command checks host performance in several functional areas
and provides either a summary or a detailed report of the results.
Health checks
The ibrix_health command runs these health checks on file serving nodes:
Pings remote file serving nodes that share a network with the test hosts. Remote servers that
are pingable might not be connected to a test host because of a Linux or StoreAll software
issue. Remote servers that are not pingable might be down or have a network problem.
If test hosts are assigned to be network interface monitors, pings their monitored interfaces to
assess the health of the connection. (For information on network interface monitoring, see
"Setting network interface options in the configuration database" (page 107)
Determines whether specified hosts can read their physical volumes.
The ibrix_health command runs this health check on both file serving nodes and StoreAll
clients:
Determines whether information maps on the tested hosts are consistent with the configuration
database.
If you include the -b option, the command also checks the health of standby servers (if configured).
Health check reports
The summary report provides an overall health check result for all tested file serving nodes and
StoreAll clients, followed by individual results. If you include the -b option, the standby servers for
all tested file serving nodes are included when the overall result is determined. The results will be
one of the following:
Passed. All tested hosts and standby servers passed every health check.
Failed. One or more tested hosts failed a health check. The health status of standby servers is
not included when this result is calculated.
Warning. A suboptimal condition that might require your attention was found on one or more
tested hosts or standby servers.
The detailed report consists of the summary report and the following additional data:
Summary of the test results
Host information such as operational state, performance data, and version data
Nondefault host tunings
Results of the health checks
By default, the Result Information field in a detailed report provides data only for health checks
that received a Failed or a Warning result. Optionally, you can expand a detailed report to provide
data about checks that received a Passed result, as well as details about the file system and
segments.
Viewing a summary health report
To view a summary health report, use the ibrix_health -l command:
ibrix_health -l [-h HOSTLIST] [-f] [-b]
By default, the command reports on all hosts. To view specific hosts, include the -h HOSTLIST
argument. To view results only for hosts that failed the check, include the -f argument. To include
standby servers in the health check, include the -b argument. To view a detailed health report,
include the -iargument.
