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.
Is there a Chef Recipe for the SPM client?

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 poorly making 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.
