getting resource usage figures via SNMP?

[marko asplund]

can i get system and per process resource consumption figures from a HP-UX 11.00 system using SNMP queries? i'm interested in cpu and io load as well as memory consumption.

Hi:
U can use the snmpwalk command.
It's free on Linux server.
snmpwalk -v 1 servername public .1.3.6.1.4.1.11.2.3.1.1.7
will get U the free memory
snmpwalk -v 1 servername public .1.3.6.1.4.1.11.2.3.1.1.3
will get U the 1 minute loading
help this can help U.

what about per process figures? is there a way of getting per process resource consumption figures via SNMP?

Hi,

Yes, you can extract the figure directly using snmpget. I had been using MRTG to interface with snmpget and graphically plot the performance graphs. If you don't wish to use MRTG to manage the OID values, you can simply run a cron script that calls snmpget to extract the OID values.

For CPU load, the OID is:
1.3.6.1.4.1.11.2.3.1.1.3.0

For available memory, the OID is:
1.3.6.1.4.1.11.2.3.1.1.7.0

For available swap, the OID i s:
1.3.6.1.4.1.11.2.3.1.1.12.0

For number of concurrent processes, the OID is:
1.3.6.1.4.1.11.2.3.1.4.1.0

For number of concurrent established TCP connections, the OID is:
1.3.6.1.2.1.6.9.0

There is a lot of system configuration and data you can extract from the HP-UX MIB file.

You will need to run the HP-UX mib2agt and please remember to disable private access and also change your public community string to a hard-to-guess phrase for security reasons.

Hope this helps. Regards.

hi,
For using any collection tools , make sure that
snmpdm daemon is running.
#ps -ef | grep snmpdm
if not
# /sbin/init.d/SnmpMaster start
Also the configuration file for the snmp daemon
is /etc/snmpd.conf

i'm a SNMP newbie so, could you give an example of how to get the process group info.

[Steven Sim Kok Leong · Accepted solution]

Hi,

The process group starts from:
1.3.6.1.4.1.11.2.3.1.4

You can perform an snmpwalk to view all the available information:

# snmpwalk my_server public .1.3.6.1.4.1.11.2.3.1.4

From the MIB file, e.g., if you want to get specifically the total number of concurrent processes, you check the processNum OID which ends with 1, thus the OID to use is:
1.3.6.1.4.1.11.2.3.1.4.1.0

# snmpget my_server public .1.3.6.1.4.1.11.2.3.1.4.1.0

Hope this helps. Regards.

yes, the .1.3.6.1.4.1.11.2.3.1.4 mib tree seems to contain the information i need. thanks.

where can i find the HP-UX mib file?

I have looked all over for the HP-UX mibs too. All I can find are mibs dataed in the '94 range. Where are these guys hiding?

[U.SivaKumar_2]

Hi,
There is wonderful GUI based MIB browser called
GETIF on windows . you can snmp connect to hp-server through this
tool.

I have a HP-UX MIB file which works great with
getif.

Thanks, I currently use GetIF; very helpfull program. My question is concerning the HPUX MIB files to use with GetIF and other SNMP tools.

Thanks
