Ruler is the component for continually evaluating rules and alerts when it exceeds the threshold. If you are familiar with Prometheus alerting rules, you understand it already. Table manager Ingester uses write ahead log (WAL) to make sure that data in memory won’t just vanish after a crash. That is, the ingester will save incoming data to the file system. After restarting, the ingester will replay all the events, then registers itself into the ring and begins its full-time job with other ingesters again. This config is what Loki will use to run, it can be invaluable for debugging issues related to configuration and curl -s "http://localhost:3100/loki/api/v1/series" --data-urlencode 'match[]={container_name=~"prometheus.*", component="server"}' --data-urlencode 'match[]={app="loki"}' | jq '.' More recently, Loki featured prominently in the Marvel comic books and cinematic universe, where he was portrayed by Tom Hiddleston. In these works, Loki was presented as the adopted son of Odin and half-brother of Thor, with whom he had a conflicted love-hate relationship. Loki resented Odin for showering love and attention on mighty Thor, who was beloved by everyone, especially the people of Earth (Midgard).
The Prose Edda book Gylfaginning tells various myths featuring Loki, including Loki's role in the birth of the horse Sleipnir and Loki's contest with Logi, fire personified.
This handler, in contrast to the deprecated /ingester/flush_shutdown handler, terminates the Loki process by default.

Two more problems are worth mentioning… since the ring is currently stored as a single value, each read or CAS operation needs to transfer the entire ring. Lastly, a separate KV store is just another dependency and component to operate. Can we do better? An alternative option to Consul or etcd may be using gossip to propagate the ring data structure across nodes. The gossip algorithm is a generic algorithm for distributing information across a set of nodes. The gossip algorithm Query scheduler is also an optional component. Even though we just mentioned that query frontend has an internal message queue that can be used to split a huge query into smaller ones, it’s probably not the most ideal way to run in terms of scalability. There are several ways you can run Loki HA, the simplest is to run the binary multiple times and specify a shared ring config in the ingester->lifecycler->ring section.Regarding to live tailing, the querier will open gRPC streams to all ingesters and starts push logs to you and still supports filters and expressions, gives you the real-time insight. ingester/shutdown triggers a shutdown of the ingester and notably will always flush any in memory chunks it holds.
Apologies as previously we weren’t paying a lot of attention to this platform for support, however that has changed and moving forward we intend to use these forums as the primary support mechanism for the community. As everything goes to plan in the TVA, it becomes clear that this is when Loki went after time-slipping in episode 1. If you’ll recall, he was pulled into the future where alarms were blaring at the TVA as he walked towards an elevator that revealed Sylvie. Just as he reached towards her, someone pruned him from behind. Well, now we know that it was Loki who did the pruning. That’s not all either, after he answers the phone, he learns that it’s O.B. on the other side wondering where they are. This is an optional component where it can handle data retention just like table manager, and when you use compactor to manage data retention, you won’t need table manager.In round 1, information is now available on 4 nodes: the original node in the middle, and three new nodes (marked as red in the picture).
