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: Filters have 1 day granularity, which means that a server will be listed under Hosts filter until 24 hours since it last sent data have passed. For example, if a server stopped sending data at 1 PM and if at 8 PM you are looking at the last 6 hours of data (for a period from 2 PM until 8 PM) you will not see data from this server on the graph, but you will still see this server listed under the Hosts filter until 1 PM on the following day. After 1 PM on the following day this server should disappear from the Hosts filter.
I rebooted my server and now I don't see any data in my graphs. What should I check?

Can SPM collect metrics even when Elasticsearch HTTP API is disabled?
A: Each SPM agent collects Elasticsearch metrics only from the local node by accessing the Stats API via HTTP. To allow only local access add the following to elasticsearch.yml. Don't forget to restart each ES node to whose elasticsearch.yml you add this.

Can I point SPM monitor to a non-localhost Elasticsearch node?
A: Yes. Adjust /opt/spm/spm-monitor/conf/spm-monitor-config-TOKEN-HERE-default.properties and change the SPM_MONITOR_ES_NODE_HOSTPORT property from the default localhost:9200 value to use an alternative hostname:port. After that restart SPM monitor (if you are running a standalone version) or Elasticsearch process(es) with embedded SPM monitor.
