How to use Event Property in Event API?

AntonioSousa — Tue, 28 Mar 2023 00:16:26 GMT

I'm trying to filter events in the Event API, using the eventSelector.

I'm using, according to the documentation:

property.myownevent("MyOwn event")

I get the following reply.

{ "error": { "code": 400, "message": "Constraints violated.", "constraintViolations": [ { "path": "eventSelector", "message": "Parse error: Unknown filter predicate found. Found near 1-based column range [1,35).", "parameterLocation": "QUERY", "location": null } ] } }

Tried other combinations, but didn't work. For reference, what the API says:

Any idea?

Hello @AntonioSousa. Same behaviour here

{
"error": {
"code": 400,
"message": "Constraints violated.",
"constraintViolations": [
{
"path": "eventSelector",
"message": "Parse error: Unknown filter predicate found. Found near 1-based column range [45,75).",
"parameterLocation": "QUERY",
"location": null
}
]
}
}

I have a ticket open for this. I will report back when I know more.

Looks like only accepts "event properties", no other properties (e.g. entity properties).

This did work for me:

property.dt.event.group_label(Created)

I have word back from the dev team. The following fields are (currently) searchable: description, source, title, allow_davis_merge, is_rootcause_relevant, release_version, group_label.

They now have a backlog item to:

- Improve the docs for this

- Investigate what (if any) additional fields can be "made searchable"

I will continue to provide feedback here whenever I hear anything.

Do anyone know if this will be improved? I want a partial match for the event title and I don't know if is possible a contains or startsWith matcher in the event selector, right now only literal match is allowed...

I am trying to filter all events for Total available space for any D drive regardless its threshold.

The propety is searchable:

property.dt.event.description(The total available space on disk D:\ is lower than 3 %)

However if I add some contain, contains or startsWith it is not a valid filter

/api/v2/events?eventSelector=property.dt.event.description.startsWith%28The%20total%20available%20space%20on%20disk%20D%3A%5C%20is%20lower%20than%203%20%25%29

{  "error": {    "code": 400,    "message": "Constraints violated.",    "constraintViolations": [      {
        "path": "eventSelector",        "message": "Parse error: Unknown filter predicate found. Found near 1-based column range [1,98).",        "parameterLocation": "QUERY",        "location": null
      }
    ]
  }
}
