HP-UX server monitoring

[sneha.irali]

Hi Team,

I have HP-UX servers enabled for monitoring using the LINUX SNMP Wizard.

I wanted to know how the CPU, Memory and disk utilization is calculated. Team here wants to do an analysis the reason for frequesntly triggered cpu, mem and disk alerts for which they need to know how is the utilization calculated on Nagios.

/backup Disk Usage Warning 1h 44m 11s 5/5 2021-10-06 05:11:18 /backup: 82%used(43691MB/53184MB) (>80%) : WARNING

CPU Usage Ok 1h 45m 44s 1/5 2021-10-06 05:15:08 1 CPU, load 24.0% < 80% : OK

Memory Usage Ok 1h 45m 27s 1/5 2021-10-06 05:15:31 Physical memory: 46%used(120564MB/262035MB) (<80%) : OK

If you pass the -v option to the plugin it will show you the OIDs and the values returned from the remote device:

Code: Select all

/usr/local/nagios/libexec/check_snmp_storage_wizard.pl -H 192.168.X.X -C 'yourcommunity' --v2c -m '^/backup$' -w 80 -c 95 -f -v
/usr/local/nagios/libexec/check_snmp_load_wizard.pl -H 192.168.X.X -C 'yourcommunity' --v2c -w 80 -c 90 -f -v
/usr/local/nagios/libexec/check_snmp_storage_wizard.pl -H 192.168.X.X -C 'yourcommunity' --v2c -m Physical -w 80 -c 90 -f -v

You would need to look inside each plugin for how the calculations are done based on that output and the OIDs that they are querying.

can you help me with the command for snmpv3..?

Hi,

I got the below o/p, I have few queries:

EDIT: For SNMPv3 they would be:

Code: Select all

/usr/local/nagios/libexec/check_snmp_storage_wizard.pl -H 192.168.X.X -L sha,aes -l snmpv3user -x 'authPass' -X 'privPass' -m '^/backup$' -w 80 -c 95 -f -v
/usr/local/nagios/libexec/check_snmp_load_wizard.pl -H 192.168.X.X -L sha,aes -l snmpv3user -x 'authPass' -X 'privPass' -w 80 -c 90 -f -v
/usr/local/nagios/libexec/check_snmp_storage_wizard.pl -H 192.168.X.X -L sha,aes -l snmpv3user -x 'authPass' -X 'privPass' -m Physical -w 80 -c 90 -f -v

This is saying your / filesystem is only 2% used, 254MBs used out of 10240MB total, which is less than the threshold of 80 defined so it's showing that info with the OK state:

Code: Select all

/: 2%used(254MB/10240MB) (<80%) : OK

This is saying you have 1 CPU, the load of that CPU is 3%, which is less than the threshold of 80 defined so it's showing that info with the OK state:

Code: Select all

1 CPU, load 3.0% < 80% : OK

This is saying you have 68% used physical memory, 22326MB used out of 32762MB total, which is less than the threshold of 80 defined so it's showing that info with the OK state:

Code: Select all

Physical memory: 68%used(22326MB/32762MB) (<80%) : OK 

Everything after the | is performance graph data, warn/critical/min/max values, that information is what is used to build the performance graphs, please see here for the performance data format:

https://nagios-plugins.org/doc/guidelines.html#AEN200

Performance Data:

Code: Select all

| '/'=254MB;8192;9216;0;10240
| cpu_prct_used=3%;80;90
| 'Physical_memory'=22326MB;26209;29486;0;32762

You can see the help sections of each plugin to determine what options it supports to make it do different things:

Code: Select all

/usr/local/nagios/libexec/check_snmp_storage_wizard.pl -h
/usr/local/nagios/libexec/check_snmp_load_wizard.pl -h
/usr/local/nagios/libexec/check_snmp_storage_wizard.pl -h
