How do I configure Collectd for SPM if I am already using it?
A: SPM requires the Collectd "csv" plugin to be enabled and configured like this:
Code Block |
---|
<Plugin csv> DataDir /opt/spm/collectd/logs StoreRates true </Plugin> |
If you are already using Collectd and if the DataDir is already pointed to some other directory, simply symlink the /spm/collectd/logs directory to the directory specified in DataDir, like this:
Code Block | ||
---|---|---|
| ||
sudo mkdir -p /opt/spm/collectd # if needed sudo ln -s /some/existing/collectd/data/dir /spm/collectd/logs |
You will also have to merge the remaining part of the Collectd config required by SPM.

I am using SPM for Solr and I don't see any data on Solr and JVM reports, what is the problem?
A: You should probably enable JMX in your Solr. Add or uncomment the <jmx /> directive in solrconfig.xml and restart Solr. See http://wiki.apache.org/solr/SolrJmx for more info.
I am using SPM for Solr and I don't see any data only in Solr Components or Errors reports, what should I do?
A: Most likely you are using standalone variant of Solr monitor. In that case, SPM monitor can't collect metrics which are available only when running in-process. If so, switch to in-process (javaagent) version of SPM monitor.
Elasticsearch Monitoring
Why doesn't the number of documents I see in SPM match the number of documents in my Elasticsearch index?

A: Kafka had great metrics in 0.7x versions and then in pre-0.8.2 the metrics had a lot of issues. In short, the MBeans Kafka exposed via JMX were named in a way that made them very difficult/impossible to parse systematically. We worked with the Kafka developers to fix that in Kafka 0.8.2 (see https://issues.apache.org/jira/browse/KAFKA-1481). To make your Kafka Producers, Consumers, and Brokers properly monitorable, you should upgrade to 0.8.2 (as soon as it is released, and it looks like that will happen in December 2014) or later.
