check_f5


checks on the F5 ServerIron load balancer.

The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on network links. 


Usage:


./check_f5.pl -H host [-C community] [-v][-d][-h][-M][-t timout]

              [--no-perf] [--no-optimise]

              [-f cachefile] [-x cacheexpiretime]

              [-m modules]


Options:


Flag

-d, --debug
        Debug mode. Use multiple times for more detail
    
-h, --help
        Show help
    
-M, --mrtg
        MRTG mode.  Also --no-mrtg for Nagios mode.
    
-t, --timeout

-f, --cache-file
        File basename for SNMP cache (/tmp/f5.cache)
    
-x, --cache-expire
        Seconds before cache becomes invalid (290)
    
--no-perf
        Disable perfstats in output
    
--no-optimise
        Retrieve entire SNMP tree for tables (use in conjunction with cache if many separate server() checks being done)
    
-m, --modules
        List modules to enable. Space separated.  Can be used multiple times if required.  See below.
    
-v, --verbose

MRTG mode


In MRTG mode, only the first module to provide a metric will be output.


Available modules:


cpu[:n][(warnpc,critpc)]
        MRTG: user and idle percent (80,90)
    
mem[ory][:percent][(warnpc,critpc)]
        MRTG: used and total bytes (or %) (80,90)
    
temp[erature][(warn,crit)]
        
    
fan
        No MRTG output
    
psu
        No MRTG output
    
health
        Same as 'cpu mem temp fan psu'
    
ssl[:server][(activewarn,activecrit)]
        MRTG: active and total SSL (500,400)
    
traffic[:server]
        MRTG: bytes in/out.  No Nagios.
    
server:name[(actvw,actvc)]
        For virt server name (500,400)
    
server:ipaddr[:port][(actvw,actvc)]
        For virt server ipaddr:port
    
server[(actvw,actvc)]
        Over ALL virtual servers (50000,40000)
    
cert[ificate][:certname][([warn,]crit)]
        Check certificate days left, no MRTG
    
conn[ections][(actvw,actvc)]
        same as 'server'
    
group
        Failover health.  No MRTG output.
    
cm
        same as 'group'
    
cache
        No output; prepare SNMP cache
    


Server checks:


For server checks, the number of active connections will be thresholded.


Next, the availability of the Server will be checked and will return WARN if not all the active pool members are available.

If the same module is used multiple times, only the first one will be used.


Example:


./check_f5.pl -H myf5 -C public -m 'cpu(80,90) server:/Production/foobar'


./check_f5.pl -H myf5 -m 'health certificates(14,7) conn(1500,2000)'
