# ungleich Matrix Setup anaylsis (2021-07-16)
## Findings
* Postgres is too slow
* Redis has timeouts that it should not have (30s)
* Login does not work
## Problems / Situation
* Cannot send messages
* Cannot login anymore
Situation:
* Added new workers to federation, sync, client before
* Added new path to nginx for client workers
* However login did not work before either
* Own login worker gets gateway timeout
* Checking if the ldap server gets a request: seems not to be the case!
* Listening on wrong source IP!
* Signin directly causes ldap traffic -> good!
* However still getting timeout
* Main worker is running at 100% cpu
* Might be the reason...
* Replication timeout messages in the log might be the main reason
*
* Incoming messages from federation seem to work / arrive!
* Browsing rooms from outside seems to be impossible
* Federation workers have high load -> let's disable federation for the moment
* redis responses not reached
## Steps
* Read up about *how it should be*
* Then compare *how it is*
* Verify the nginx configuration
* Verify the worker configuration
* Verify that all needed workers are up and running
* I think we were missing the persister before ?
* But there is no configuration for it
## Should be state definition (based on research)
* 1 main worker running on port 8008
* According to https://matrix.org/blog/2020/11/03/how-we-fixed-synapses-scalability
* One or more event persisters?
* Redis is up and running
## *IS* state research (what is on our system)
* **NO PASSWORD** for worker_replication_secret
* Redis is up and running
* Main process
* 1 main worker running on port 9093 with [replication]
* 1 main worker running on port 8008 with [federation,client,metrics]
* Workers
* background, metrics, port 8086
* run_background_tasks_on: background in the homeserver.yaml
* Jul 16 02:10:07 ungleich-v6 matrix-synapse-background[2322]: Config is missing macaroon_secret_key
* Jul 16 02:10:08 ungleich-v6 matrix-synapse-background[2322]: 2021-07-16 02:10:08,820 - synapse.storage.engines.postgres - 69 - WARNING - main- Database has incorrect collation of 'C.UTF-8'. Should be 'C'
* client1: metrics+client port 8084
* client2: metrics+client port 8092
* event1: metrics port 8082
* federation1: metrics+federation 8085
* federation2: metrics+federation 8087
* federation3: metrics+federation 8095
* federation4: metrics+federation 8096
* sync1: metrics+client port 8083
* sync2: metrics+client port 8093
* sync3: metrics+client port 8094
* **NEW WORKERS added 2021-07-16**
* login1: metrics+client port 8097
* Other synapse settings
* pushing is still in the main process
* Persisting seems to be in the main process
* No MEDIA worker (could be very helpful!) synapse.app.media_repository
* nginx upstreams
* inbound_federation: 8085, 8087, 8095, 8096: ok
* sync_workers: 8083, 8093, 8094: ok
* federation: 8085, 8087, 8095, 8096: ok
* client_workers: 8084, 8092: ok
* **event_sending: 8082: UNCLEAR**
* nginx config / paths
* /sync and /initialSync for same user
* /sync with ?since can go to different instances
* Isolating the login syncs vs. regular syncs
* Federation and client requests can be balanced via simple round robin.
* ^/_matrix/federation/v1/send/ (INBOUND federation ) should be balanced by source IP
* Registration/login requests can be handled separately purely to help ensure that unexpected load doesn't affect new logins and sign ups.
* event sending requests can be balanced by the room ID in the URI - the room ID is the path component after /rooms/
## Should vs. IS table
| Should | IS | Notes |
|---|---|---|
| main worker port: replication | yes |
| main worker NO other ports | NO | Also listening on 8008 |
| workers should be on ::1 | NO | Are on :: for, allowing world access to /metrics |
## Open todos
* background: Fix Jul 16 02:10:08 ungleich-v6 matrix-synapse-background[2322]: 2021-07-16 02:10:08,820 - synapse.storage.engines.postgres - 69 - WARNING - main- Database has incorrect collation of 'C.UTF-8'. Should be 'C'
* background: Fix Config is missing macaroon_secret_key
## Actions taken 2021-07-16
* Remove port 8008 from main worker, restart (0946)
* Result: messages can still not be sent from our instance
