Jaeger-query URL to get all traces in last X minutes

[Aditi Ghag]

Hi,

I'm invoking this Jaeger query to get all the traces recorded in the last 20 minutes - 

wget -O -  http://<jaeger-query-cluster-ip>:16686/api/traces?service=orders&lookback=20m&limit=1

It goes printing lot of text on the screen by ignoring url parameters. 

wget -O -  http://<jaeger-query-cluster-ip>:16686/api/traces?lookback=20m&limit=1

Connecting to <ip>:16686... connected.

HTTP request sent, awaiting response... 400 Bad Request

2018-12-04 15:49:41 ERROR 400: Bad Request.

What's the url endpoint to get all the traces recorded in last X minutes for all the services?

Also, I need to get the output in a JSON format.

From a quick look at the code, it looks like the lookback param may only be used in the UI to set the start param. So you might want to create an issue on https://github.com/jaegertracing/jaeger to have this also supported on the backend - and consider contributing a PR :)

When I need to find the exact URL for an API call, I run the query from the UI and check chrome dev tools for the URL of the Ajax request.

Thanks Yuri and Gary.

Yuri,

That's exactly what I ended up doing. :)

Anyway as it turns out, it's not possible to get all the traces unless you specify a service.

This is what worked for me - 

curl -s 'http://10.99.29.154:16686/api/traces?service=orders&lookback=20m&prettyPrint=true&limit=1'

Without setting prettyPrint to true, the output is printed in plain text format (not JSON) and since I set the lookback parameter to 20m, there were lot of traces captured. I also had a typo in my last update, I had actually set the limit to 10.
