Version Warning

This article applies to OpenNMS 1.2.x. If you are running a newer version, please note that the hard-coded instance identifiers used in this article are no longer necessary. In versions of OpenNMS from about 1.3.9 onwards, all the information described in this article should be present out of the box. The only configuration changes that might be necessary are those to the snmpd.conf files on the managed systems.

If you insist on trying to apply this article to a recent version of OpenNMS, please note that the "type" sub-property in snmp-graph.properties needs to be nodeSnmp instead of node.

Based off a message from Aitor Goiri to the opennms-discuss list

From the opennms-discuss list, Aitor Goiri writes:

I prefer to customize the /etc/snmp/snmpd.conf file by adding (for example): 

disk / 
disk /home 
disk /usr 
disk /opt 
disk /var

I am taking the liberty of modifying the rest of Aitor's post with a more detailed discussion of this topic.

I want to provide a step by step procedure for configuring disk space information on servers with different partitions. This consists of modifying the net-snmp agent, then setting up data collection, to generating graphs and finally setting thresholds.

Partition layout

Suppose there are the following paritions on three different machines:

1st machine 

/ 
/usr 
/var 
/tmp 
/home 
/logs 
/hyperlib 
/webroot

2nd machine 

/ 
/usr 
/var 
/tmp 
/home 
/usr/sys/inst.images 
/apps 
/database 
/usr/netscape 
/proc 
/opt 
/hyperlib

3rd machine 

/ 
/usr 
/var 
/tmp 
/home 
/proc 
/opt 
/hyperlib 
/backitems 
/topic 
/usr/netscape 
/intake

Configuration

Step 1: Setting up net-snmp

Edit the snmpd.conf file on each machine. Find the section of the file that talks about the "disk" directive.

On the 1st machine, you would add: 

 disk / 
 disk /usr 
 disk /var 
 disk /tmp 
 disk /home 
 disk /logs 
 disk /hyperlib 
 disk /webroot

Edit the snmpd.conf file on the second 2nd machine and add: 

 disk / 
 disk /usr 
 disk /var 
 disk /tmp 
 disk /home 
 disk /usr/sys/inst.images 
 disk /apps 
 disk /database 
 disk /usr/netscape 
 disk /proc 
 disk /opt 
 disk /hyperlib

Edit the snmpd.conf file on the 3rd machine and add: 

 disk / 
 disk /usr 
 disk /var 
 disk /tmp 
 disk /home 
 disk /proc 
 disk /opt 
 disk /hyperlib 
 disk /backitems 
 disk /topic 
 disk /usr/netscape 
 disk /intake

Then restart the snmpd process on all three devices.

Step 2: Setting up the datacollection-config.xml file

NOTE: You may want to backup datacollection-config.xml, collectd-configuration.xml, thresholds.xml and snmp-graph.properties before continuing.

For this step you will need to know the systemOID for the systems. You should be able to snmpwalk the system tree to retrieve this. My guess is that it will start out with something like: .1.3.6.1.4.1.8072 or .1.3.6.1.4.1.2021.

You can run the following command to get your sysObjectID

snmpget -On -c public -v 1 host_ip sysObjectID.0

The value returned will go into the "<sysoidMask>[system OID from above]</sysoidMask>" section.

On the OpenNMS system, edit the datacollection-config.xml file and add the following after the next to the last line </snmp-collection>: 

        <snmp-collection name="System-1"
                maxVarsPerPdu = "50"

NOTE: The name in the "alias" field is limited to 19 characters, and replace the [system OID from above] with the appropriate string.

The whole concept here is to create RRD files that include the name of the disk partition we wish to measure.

Step 3: Editing the collectd-configuration file

On the OpenNMS system, edit the collectd-configuration file and add the following packages: 

        <package name="System-1">
                <filter>IPADDR IPLIKE *.*.*.*</filter>
                <specific>[IP address of System 1]</specific>

                <service name="SNMP" interval="300000" user-defined="true" status="on">
                        <parameter key="collection" value="System-1"/>
                        <parameter key="port" value="161"/>
                        <parameter key="retry" value="3"/>
                        <parameter key="timeout" value="3000"/>

You don't need a separate group for every server, just one for each one with a different partition setup. Use multiple <specific> tags to add or remove servers from the group.

Finally, find the "reports=" line at the top of that file and insert: 

disk.root, disk.rootpercent, disk.usr, disk.usrpercent, \
disk.var, disk.varpercent, disk.tmp, disk.tmppercent, \
disk.home, disk.homepercent, disk.logs, disk.logspercent, \

disk.opt, disk.optpercent, \ 
disk.bckitems, disk.bckitemspercent, disk.topic, disk.topicpercent, \ 
disk.intake, disk.intakepercent, disk.netscape, disk.netscapepercent \

on the line *before* 

 hrMemory, hrNumUsers, hrSystemProcesses, hrSystemUptime, cpuRaw

NOTE: Do not have any whitespace after the "\" characters, and if "Calculating ..." shows up in the webUI and won't go away, you probably have a mistake in this file.

Step 5: Thresholds

On the OpenNMS machine, edit the thresholds.xml file:

Just before the </group> tag at the bottom of the "default-snmp" group, add: 

                <threshold type="high" ds-name="disk-root-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-usr-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-var-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-tmp-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-home-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-logs-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-hyperlib-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-webroot-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-instimg-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-apps-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-database-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-proc-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-opt-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-bckitems-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-topic-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-intake-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>
                <threshold type="high" ds-name="disk-netscape-pcent"  ds-type="node" value="90" rearm="70" trigger="2"/>


This will cause a highThreshold event when disk space reaches 90% on any volume. Tune as needed.
