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
I improve performance/reduce load ofSPM client
by usinguse HTTP instead of HTTPS
to sendto send metrics from my servers?
A: Yes. Since version 1.22.0, SPM sender by default uses HTTPS to send metrics data to Sematext servers. If you are OK prefer to use HTTP instead (for example, in if you are running SPM on - premises setups, or if you don't need metric data to be encrypted when sending being sent to SPM over the Internet), you can adjust that in file in /opt/spm/properties/spm-sender.properties by changing protocol to http in property:
