beorn7	c2e9a151ab	Make all rule links link to the "Console" tab rather than "Graph" Clicking on a rule, either the name or the expression, opens the rule result (or the corresponding expression, repsectively) in the expression browser. This should by default happen in the console tab, as, more often than not, displaying it in the graph tab runs into a timeout.	7 years ago

Matt Palmer	3369422327	Improve DNS response handling to prevent "stuck" records [Fixes #2799 ] (#3138 ) The problem reported in #2799 was that in the event that all records for a name were removed, the target group was never updated to be the "empty" set. Essentially, whatever Prometheus last saw as a non-empty list of targets would stay that way forever (or at least until Prometheus restarted...). This came about because of a fairly naive interpretation of what a valid-looking DNS response actually looked like -- essentially, the only valid DNS responses were ones that had a non-empty record list. That's fine as long as your config always lists only target names which have non-empty record sets; if your environment happens to legitimately have empty record sets sometimes, all hell breaks loose (otherwise-cleanly shutdown systems trigger up==0 alerts, for instance). This patch is a refactoring of the DNS lookup behaviour that maintains existing behaviour with regard to search paths, but correctly handles empty and non-existent record sets. RFC1034 s4.3.1 says there's three ways a recursive DNS server can respond: 1. Here is your answer (possibly an empty answer, because of the way DNS considers all records for a name, regardless of type, when deciding whether the name exists). 2. There is no spoon (the name you asked for definitely does not exist). 3. I am a teapot (something has gone terribly wrong). Situations 1 and 2 are fine and dandy; whatever the answer is (empty or otherwise) is the list of targets. If something has gone wrong, then we shouldn't go updating the target list because we don't really know what the target list should be. Multiple DNS servers to query is a straightforward augmentation; if you get an error, then try the next server in the list, until you get an answer or run out servers to ask. Only if all the servers return errors should you return an error to the calling code. Where things get complicated is the search path. In order to be able to confidently say, "this name does not exist anywhere, you can remove all the targets for this name because it's definitely GORN", at least one server for all the possible names need to return either successful-but-empty responses, or NXDOMAIN. If any name errors out, then -- since that one might have been the one where the records came from -- you need to say "maintain the status quo until we get a known-good response". It is possible, though unlikely, that a poorly-configured DNS setup (say, one which had a domain in its search path for which all configured recursive resolvers respond with REFUSED) could result in the same "stuck" records problem we're solving here, but the DNS configuration should be fixed in that case, and there's nothing we can do in Prometheus itself to fix the problem. I've tested this patch on a local scratch instance in all the various ways I can think of: 1. Adding records (targets get scraped) 2. Adding records of a different type 3. Remove records of the requested type, leaving other type records intact (targets don't get scraped) 4. Remove all records for the name (targets don't get scraped) 5. Shutdown the resolver (targets still get scraped) There's no automated test suite additions, because there isn't a test suite for DNS discovery, and I was stretching my Go skills to the limit to make this happen; mock objects are beyond me.	7 years ago

Julius Volz	8ebeed0b44	remote: Expose ClientConfig type (#3165 ) The Client type is already exposed, but can't be used without the config for it also being exposed. Using the remote.Client from other programs is useful to do full end-to-end tests of Prometheus's remote protocol against adapter implementations.	7 years ago

Tom Wilkie	4f8efdbd59	Prevent number of remote write shards from going negative. This can happen in the situation where the system scales up the number of shards massively (to deal with some backlog), then scales it down again as the number of samples sent during the time period is less than the number received.	7 years ago

Matt Bostock	e758260986	Marathon SD: Set port index label The changes [1][] to Marathon service discovery to support multiple ports mean that Prometheus now attempts to scrape all ports belonging to a Marathon service. You can use port definition or port mapping labels to filter out which ports to scrape but that requires service owners to update their Marathon configuration. To allow for a smoother migration path, add a `__meta_marathon_port_index` label, whose value is set to the port's sequential index integer. For example, PORT0 has the value `0`, PORT1 has the value `1`, and so on. This allows you to support scraping both the first available port (the previous behaviour) in addition to ports with a `metrics` label. For example, here's the relabel configuration we might use with this patch: - action: keep source_labels: ['__meta_marathon_port_definition_label_metrics', '__meta_marathon_port_mapping_label_metrics', '__meta_marathon_port_index'] # Keep if port mapping or definition has a 'metrics' label with any # non-empty value, or if no 'metrics' port label exists but this is the # service's first available port regex: ([^;]+;;[^;]+\|;[^;]+;[^;]+\|;;0) This assumes that the Marathon API returns the ports in sorted order (matching PORT0, PORT1, etc), which it appears that it does.
