beorn7	5b53aa1108	style: Replace `else if` cascades with `switch` Wiser coders than myself have come to the conclusion that a `switch` statement is almost always superior to a statement that includes any `else if`. The exceptions that I have found in our codebase are just these two: * The `if else` is followed by an additional statement before the next condition (separated by a `;`). * The whole thing is within a `for` loop and `break` statements are used. In this case, using `switch` would require tagging the `for` loop, which probably tips the balance. Why are `switch` statements more readable? For one, fewer curly braces. But more importantly, the conditions all have the same alignment, so the whole thing follows the natural flow of going down a list of conditions. With `else if`, in contrast, all conditions but the first are "hidden" behind `} else if `, harder to spot and (for no good reason) presented differently from the first condition. I'm sure the aforemention wise coders can list even more reasons. In any case, I like it so much that I have found myself recommending it in code reviews. I would like to make it a habit in our code base, without making it a hard requirement that we would test on the CI. But for that, there has to be a role model, so this commit eliminates all `if else` occurrences, unless it is autogenerated code or fits one of the exceptions above.

Jens Erat	728fdc959e	Kubernetes SD: disable resync timer While originally the resync period also forced refreshing from Kubernetes API server, this has been removed for some years now because watching the API server got more stable [1]. Today, this just results in all entities being sent to the service discovery again, which is valid from a general Prometheus perspective, but results in unnecessary CPU load and also breaks service discovery metrics. In especially, this makes monitoring "do we actually observe changes from Kubernetes API server" impossible (receiving constant updates from Kubernetes service discovery is a pretty valid assumption, for example nodes get frequent status updates, ...).

Georg Gadinger	c85efa02d9	Fix k8s target discovery when not running inside k8s When using Kubernetes service discovery on a Prometheus instance that's not running inside Kubernetes, the creation of the service discovery fails with a "no such file or directory" error as the special `/var/run/secrets/kubernetes.io/serviceaccount/namespace` file is not there. This commit moves the code that reads this file into the if-branch where no `APIServer.URL` is given (that one basically makes Prometheus assume it is running inside of a Kubernetes cluster).

Alexey Shumkin	73ddf603af	discovery/kubernetes: Fix valid label selector causing config error Label selector can be "set-based"(https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#set-based-requirement) but such a selector causes Prometheus start failure with the "unexpected error: parsing YAML file ...: invalid selector: 'foo in (bar,baz)'; can't understand 'baz)'"-like error. This is caused by the `fields.ParseSelector(string)` function that simply splits an expression as a CSV-list, so a comma confuses such a parsing method and lead to the error. Use `labels.Parse(string)` to use a valid lexer to parse a selector expression. Closes #8284. Signed-off-by: Alexey Shumkin <Alex.Crezoff@gmail.com>	4 years ago

Daniele Sluijters	f25a6baedb	remote: Set User-Agent header in requests (#4891 ) Currently Prometheus requests show up with a UA of Go-http-client/1.1 which isn't super helpful. Though the X-Prometheus-Remote-* headers exist they need to be explicitly configured when logging the request in order to be able to deduce this is a request originating from Prometheus. By setting the header we remove this ambiguity and make default server logs just a bit more useful. This also updates a few other places to consistently capitalize the 'P' in the user agent, as well as ensure we set a UA to begin with.
