Monitoring with NET-SNMP

[grabber]

Thanks

[patrickpeng]

hello
I am a new user of zabbix-1.1, till now , I still do not know how to configure the snmp-agent, can anybody who can help me? With zabbix-agent, I can monitor it very well, but for snmp, do I need to install anything, and with snmp.conf, do I need to change anything. I created a new host, set its port to 161, let it link to SNMP_t, anything else to do? Please help me.

But since the MIB definition is a STRING, I cannot graph the results.

SNMPd is giving wrong value for cpu utilization

Hi,
I configured following line in snmpd.conf file
extend <MIBIID> cpu /tmp/cpuutil to get cpu utilization.
and cpuutil file contains following line:
sar - u 1 | grep Average|awk '{print ($3 + $4 + $5 + $6)}'

But snmp is not giving proper values. Is this the bug in my code or in snmp. Please help to fix this bug.

Thanks,
Manu.V

You can monitor CPU utilisation (%) with these OID :

Instant monitor, not an average :

UCD-SNMP-MIB::ssCpuRawUser.0 -> Number of timeticks used by users's process (AIX, Solaris, Linux, HP-UX)
UCD-SNMP-MIB::ssCpuRawSystem.0 -> Number of timeticks used by system's process (AIX, Solaris, Linux, HP-UX)
UCD-SNMP-MIB::ssCpuRawIdle.0 -> Number of timeticks unused (AIX, Solaris, Linux, HP-UX)
UCD-SNMP-MIB::ssCpuRawWait.0-> Number of timeticks used by process waiting (AIX, Solaris, HP-UX)
UCD-SNMP-MIB::ssCpuRawNice.0-> Number of timeticks used by nice process (Linux, HP-UX)
UCD-SNMP-MIB::ssCpuRawKernel.0 -> Number of timeticks used by kernel process (AIX, Solaris, Linux, HP-UX)

Configure the item with an OID, chose a custom multiplier of :
- 1 * 100 / (delay between checks * number of timeticks per second * number of CPU) for Linux
- 1 * 100 * number of CPU / (delay between checks * number of timeticks per second) for HP-UX
- 1 * 100 / (delay between checks * number of timeticks per second) for AIX and Solaris
store 'Delta Simple Change'.
To get the number of timeticks per second, use 'getconf CLK_TCK'. It's always 100 on hosts I've tested.
For example, with CLK_TCK=100 (Linux i386), check every 10 seconds, 2 CPU, the custom multiplier is 0.05.
For Linux, it's the logical number of CPU displayed by command 'top', not the physical number.

Could you help me with FreeBSD OS custom multiplier?
# getconf CLK_TCK
128

delay between checks is 30s.
