Metricbeat doesn't recognize the process

Hi @xyz2

So what may be happening is that you are using the default system.yml (system module) see with the defaults for the process metric set so you are probably using the Top N settings and sometimes the process you are looking for is in the Top 5 other times it is not

- module: system
  period: 10s
  metricsets:
    - cpu
    - load
    - memory
    - network
    - process
    - process_summary
    - socket_summary
    #- entropy
    #- core
    #- diskio
    #- socket
    #- service
    #- users
  process.include_top_n:
    by_cpu: 5      # include top 5 processes by CPU
    by_memory: 5   # include top 5 processes by memory

Above are the default settings

process.include_top_n

These options allow you to filter out all processes that are not in the top N by CPU or memory, in order to reduce the number of documents created. If both the by_cpu and by_memory options are used, the union of the two sets is included.

If you want all processes take out the top and use something like this

processes

When the process metricset is enabled, you can use the processes option to define a list of regexp expressions to filter the processes that are reported. For more complex filtering, you should use the processors configuration option. See Processors for more information.

The following example config returns metrics for all processes:

processes: ['.*']

Careful that might return A LOT of data ...

So you can adjust there are many settings to adjust it depends on what you want.
