Comment 4 for bug 2044062

cos-tools' document has an example to convert a query, but it doesn't touch anything about the job name.

https://github.com/canonical/cos-tool/blob/main/README.md

> job:request_latency_seconds:mean5m{job=\"myjob\"} > 0.5

> job:request_latency_seconds:mean5m{job="myjob",juju_application="proxy",juju_model="lma",juju_model_uuid="12345",juju_unit="proxy/1"} > 0.5

Not sure how the job name is supposed to be written in the COS world like with a special variable or a job name shouldn't be used at all.
