Specify which processes to monitor
editSpecify which processes to monitor
editThis section of the packetbeat.yml config file is optional, but configuring
the processes enables Packetbeat to show you not only the servers that the
traffic is flowing between, but also the processes. Packetbeat can even show you
the traffic between two processes running on the same host, which is
particularly useful when you have many services running on the same server. By
default, process enrichment is disabled.
When Packetbeat starts, and then periodically afterwards, it scans the process table for processes that match the configuration file. For each of these processes, it monitors which file descriptors it has opened. When a new packet is captured, it reads the list of active TCP and UDP connections and matches the corresponding one with the list of file descriptors.
All this information is available via system interfaces: The /proc file system
in Linux and the IP Helper API (iphlpapi.dll) on Windows, so Packetbeat
doesn’t need a kernel module.
Process monitoring is currently only supported on Linux and Windows systems. Packetbeat automatically disables process monitoring when it detects other operating systems.
Example configuration:
packetbeat.procs.enabled: true
When the process monitor is enabled, it will enrich all the events whose source
or destination is a local process. The source.process and/or
destination.process fields will be added to an event, when the server side or
client side of the connection belong to a local process, respectively.
Configuration options
editYou can specify the following process monitoring options in the monitored
section of the packetbeat.yml config file to customize the name of process:
process
editThe name of the process as it will appear in the published transactions. The name doesn’t have to match the name of the executable, so feel free to choose something more descriptive (for example, "myapp" instead of "gunicorn").
cmdline_grep
editThe name used to identify the process at run time. When Packetbeat starts, and then
periodically afterwards, it scans the process table for
processes that match the values specified for this option. The match is done against the
process' command line as read from /proc/<pid>/cmdline.
shutdown_timeout
editHow long Packetbeat waits on shutdown. By default, this option is disabled. Packetbeat
will wait for shutdown_timeout and then close. It will not track if all events were sent
previously.
Example configuration:
packetbeat.shutdown_timeout: 5s
