the application doesn't show the new graphs defined when we apply the changes to another server

We had problem with graphics on OpenNMS before.
We couldn’t draw Percentil graph because OpenNMS couldn’t understand some commands (VDEF and PERCENTIL) and we couldn’t draw graphs based on Entity Sensor oids because OpenNMS couldn’t catch the information.

We solved these problems changing JRobin compiler for rrd and installing Entity Sensor mibs (CISCO-ENTITY-SENSOR-MIB and ENTITY-MIB) on OpenNMS.

We are implanting now the same solution at the production environment server, but neither of these new graphs were shown.

We’ve looked at different logs (webmap, snmp, output and collect) but there isn't any relevant information.

We've also looked at var/rrd/snmp/node_subfiles and there's no presence of any Entity Sensor graph, but we can retrieve values from this oid's through snmpwalk command.

At var/rrd/snmp/node_subfiles we do have rrd files for percentil graph definition, but when we open the resource graph section for these nodes (and snmp interfaces) on the web application, the percentil graph is not shown.

Could anybody tell us where the problem is?, do you know what can cause these problems and/or how to fix them?


Thank you in advance for any help you can provide

Hey Sandra,

if I understud your question correctly, then you have all the rrds on the system.
If some rrds for a graph are missing, it is not displayed at all and no messages would endup in any log.

So doubble check that you have ALL rrds for your graph.

Check if your graph definition has a reference entry in the report list at the top of the graph.properties file.
