Process input plugin allows you to check how healthy a process is. It does so by performing a service check at every certain interval of time specified by the user.
The Process metrics plugin creates metrics that are log-based, such as JSON payload. For Prometheus-based metrics, see the Node Exporter Metrics input plugin.
The plugin supports the following configuration parameters:
Proc_Name
Name of the target Process to check.
Interval_Sec
Interval in seconds between the service checks. Default value is 1.
Interval_Nsec
Specify a nanoseconds interval for service checks, it works in conjunction with the Interval_Sec configuration key. Default value is 0.
Alert
If enabled, it will only generate messages if the target process is down. By default this option is disabled.
Fd
If enabled, a number of fd is appended to each records. Default value is true.
Mem
If enabled, memory usage of the process is appended to each records. Default value is true.
Threaded
Indicates whether to run this input in its own thread. Default: false.
