HP Insight Management Agents for Linux - Installation Guide and Release Notes - HP Integrity Servers with Linux (March 2010)
Obtaining the Community String
You can obtain the rwcommunity string by viewing the /etc/snmp/snmpd.conf on your
system and finding the line similar to the following:
rwcommunity lYABuwPNFgmVCSkH 127.0.0.1
In this example, the rwcommunity string is set to lYABuwPNFgmVCSkH.
Viewing a Polling Interval
You can view the current polling interval for an agent with the snmpget command as follows:
# snmpget -mALL -v1 -c<community string> localhost <OID>.0
For example, to view the NIC agent polling interval and using the community string in the
previous example, the command is as follows:
# snmpget -mALL -v1 -c lYABuwPNFgmVCSkH localhost cpqNicOsCommonPollFreq.0
CPQNIC-MIB::cpqSeOsCommonPollFreq.0 = INTEGER: 52
The response indicates that a 30 second polling interval is set for the NIC agent.
Changing a Polling Interval
The valid range that you can set polling intervals to is 0 - 65535 seconds. Any value within this
range is valid and values outside the range are rejected. You can change the polling interval
using either of the following methods:
Using the snmpset Command:
You can change the current polling interval for each agent with the snmpget command as
follows:
snmpset -mALL -v1 -c<community string> localhost cpq<OID>CommonPollFreq.0 = <new interval>
For example, to change the NIC agent polling interval to 52 seconds and using the community
string in the previous example, the command is as follows:
# snmpset -mALL -v1 -c lYABuwPNFgmVCSkH localhost cpqNicOsCommonPollFreq.0 = 52
CPQNIC-MIB::cpqSeOsCommonPollFreq.0 = INTEGER: 52
The response indicates that your set request to change the NIC agent polling interval to 52
seconds was successful.
Using the Environment Variable:
The environment variable, HPIMA_POLLFREQ, can be set to a global polling interval to operate
all HP Insight Management Agents with the same polling frequency. You can set this
environment variable using the following command format:
# HPIMA_POLLFREQ=<new interval> /etc/init.d/hpima restart
For example, to set all agent polling intervals to 60 seconds the command is as follows:
# HPIMA_POLLFREQ=60 /etc/init.d/hpima restart
All HP Insight Management Agent polling intervals are now set to 60 seconds and each agent
process is restarted by the /etc/init.d/hpima/restart command.
Additionally, you can use the HPIMA_POLLFREQ variable to set the polling frequency for an
individual agent using the following command format:
# HPIMA_POLLFREQ=<new interval> /etc/init.d/hpima restart <agent>
where:
Is an agent string with the 'hpima' prefix removed from the process names as described in Table 2-1
(page 13). For example, the agent for hpimanicd is nicd.
agent
For example, to set all the NIC agent polling interval to 180 seconds the command is as
follows:
# HPIMA_POLLFREQ=180 /etc/init.d/hpima restart nicd
