Add process metadata
editAdd process metadata
editThe add_process_metadata
processor enriches events with information from running
processes, identified by their process ID (PID).
processors: - add_process_metadata: match_pids: [system.process.ppid] target: system.process.parent
The fields added to the event look as follows:
"process": { "name": "systemd", "title": "/usr/lib/systemd/systemd --switched-root --system --deserialize 22", "exe": "/usr/lib/systemd/systemd", "args": ["/usr/lib/systemd/systemd", "--switched-root", "--system", "--deserialize", "22"], "pid": 1, "ppid": 0, "start_time": "2018-08-22T08:44:50.684Z", }
Optionally, the process environment can be included, too:
... "env": { "HOME": "/", "TERM": "linux", "BOOT_IMAGE": "/boot/vmlinuz-4.11.8-300.fc26.x86_64", "LANG": "en_US.UTF-8", } ...
It has the following settings:
-
match_pids
- List of fields to lookup for a PID. The processor will search the list sequentially until the field is found in the current event, and the PID lookup will be applied to the value of this field.
-
target
-
(Optional) Destination prefix where the
process
object will be created. The default is the event’s root. -
include_fields
-
(Optional) List of fields to add. By default, the processor
will add all the available fields except
process.env
. -
ignore_missing
-
(Optional) When set to
false
, events that don’t contain any of the fields in match_pids will be discarded and an error will be generated. By default, this condition is ignored. -
overwrite_keys
-
(Optional) By default, if a target field already exists, it
will not be overwritten and an error will be logged. If
overwrite_keys
is set totrue
, this condition will be ignored. -
restricted_fields
-
(Optional) By default, the
process.env
field is not output, to avoid leaking sensitive data. Ifrestricted_fields
istrue
, the field will be present in the output.
