Availability (Up/Down) Status for Entities Monitored by Telegraf
For most entities monitored by Telegraf, availability is turned off by default, but can be enabled by setting the appropriate emd.properties file property. For a specific subset of entities where the concept of “availability” does not apply, availability processing cannot be enabled.
Availability processing is not applicable (and cannot be enabled) for the following Telegraf plug-ins:
- cpu
- disk
- diskio
- interface
- kernel
- mem
- swap
- system
Availability processing for all other Telegraf plug-ins is set to “not applicable” by default, but can be enabled via the following property settings in the emd.properties file.
