[opennms-discuss] OpenNMS Squid monitoring - could not load class

[Steven Vacaroaia]

Hi,

I am unable to start OpenNMS after I enable squid data collection
Any help / suggestions will be greatly appreciated

I can snmpwalk squid OID
I used the info/config from the following sites

https://wiki.opennms.org/wiki/Squid_Data_Collection
http://www.hemmler.org/opennms/squid-ueberwachen/


The error message is

Could not load class 'org.opennms.netmgt.dao.support.IndexStorageStrategy'
for resource type 'cacheMedianSvcTable'


see below a bigger excerpt from the output.log

Hi Steven,

the IndexStorageStrategy has moved from

org.opennms.netmgt.dao.support.IndexStorageStrategy
to
org.opennms.netmgt.collection.support.IndexStorageStrategy

so the wiki seems to be outdated. Just change this in the datacollection config and opennms should start again.
