Graphing uptime?

[phill]

For HTTP request logs I have the HTTP status and I’d love to create a graph that represents the sum of successful requests over the total requests to give an uptime percentage. I can certainly create a bar graph that gives me counts for each status, but I’d love to output a % (either as a graph visualization, or even as a single number). It’s unclear to me how I might create an aggregation that does this math. Is it possible?

Hello && Welcome

I’m assuming your looking for something like this?

By using the aggregation widget, you can configure it like this.

Just a side note this is Graylog 4.0+, ES 7.10, and MongoDb 4.4.
Dont know if you have seen this.

Hope that helps

EDIT:

@phill

I havent tried that type of configuration out, and I’m not sure Graylog can do those types of calulation on widget. I do know Zabbix can.

Ah, this makes sense! Since I probably can’t do the math in the aggregation to sum the 2XX, 3XX, 4XX requests I could do that in the pipeline and create a field which is “good/bad” on each request log and then get a % of good requests value out of this visualization that could be used as an uptime measurement.

Maybe this might help

You might be able to use some of these function here. Just an idea
