Is it possible to modify inclusions or exclusions for Host Metrics without restarting PSM?
According to the following dynaTrace document, it could edit the System Profile to modify the inclusions or exclusions for host metrics. But it must do it when Dynatrace Server is stopped and then restart it.
This is extremely inconvenient for the customer who is not allowed to restart PSM frequently. E.g., one of the customer has the following scenario:
- The PSM server is monitoring multiple servers for multiple PTC products (Windchill, Integrity, etc.)
- The customer needs to include/exclude some disks from monitoring frequently, because different servers frequently have storage related modification.
- Stopping PSM server will affect monitoring for all PTC products.

Inclusions or Exclusions for Host Metrics
To exclude specific disks from monitoring (or explicitly include disks that would otherwise be excluded), edit the specific System Profile file (DT_HOME/server/conf/profiles/<profileName>.profile.xml), where these properties are persisted.
Stop the Dynatrace Server before you edit the System Profile, so the changes don´t get overwritten. You must restart to apply the changes.
<systemprofile ...> <genericagentproperties>
<property value="disk(linux,*,/tmp); disk(linux,*,/var/tmp);disk(linux,*,/run); disk(linux,*,/var/run)" key="hostmetrics.inclusions" />
<property value="disk(linux,tmpfs,*); disk(linux,*,/dev); disk(linux,cgroup,*); disk(linux,debugfs,*); nic(solaris,mac)" key="hostmetrics.exclusions" />
</genericagentproperties>
</systemprofile>

The above also shows the default inclusions and exclusions.
