Help: $ ./check_cisco_nexus_cpu.pl -h ############################################## # ADEO Services # ############################################## Usage:./check_cisco_nexus_cpu.pl -H (--hostname) Hostname to query - (required) -C (--community) SNMP read community (defaults to public, used with SNMP v1 and v2c -v (--snmp_version) 1 for SNMP v1 (default) 2 for SNMP v2c -k (--key) snmp V3 key -p (--password) snmp V3 password -u (--username) snmp v3 username -V (--version) Plugin version -h (--help) usage help
-i (--sysdescr) use sysdescr instead of sysname for label display -w (--warning) pass 3 values for warning threshold (5 seconds, 1 minute and 5 minutes cpu average usage in %) -c (--critical) pass 3 values for critical threshold (5 seconds, 1 minute and 5 minutes cpu average usage in %)
-d (--debug) debug level (1 -> 15)
Example usage: ./check_cisco_nexus_cpu.pl -H 10.XX.XX.XX -C SnmpV1V2Community -v 2 -w 80,70,60 -c 90,80,70
The sysName is written on output but you can choose to display the sysDescr instead with -i (sysDescr give Cisco nexus model and firmware release).
Works on Nexus 3064 NX-OS 7.x without any problems.
Tested with Nexus 5000 and works fine... I think the output could be more comfortable to read. And the warning and critical thresholds are necessary, otherwise the script will throw some errors like "Use of uninitialized value".
I tried this on Nexus 5010 but getting errors: Use of uninitialized value $five_sec in numeric gt (>) at ./check_cisco_nexus_cpu.pl line 192. Use of uninitialized value $one_min in numeric gt (>) at ./check_cisco_nexus_cpu.pl line 192.
