similar to: director: backend health monitoring

Timo et al; The last bit of functionality that the Dovecot director is missing compared to our existing load balancers is mailserver health monitoring. As I understand it, if a mailserver goes down, Dovecot does not take any action to route connections around the offline node, and will keep trying to proxy clients to it. Since we're hoping to cut over to Directors soon, but don't want to

Does Dovecot Director health monitoring of backend servers ? Or is poolmon (http://www.dovecot.org/list/dovecot/2010-August/051946.html) the best option for this? Maybe Ldirectord? Thanks! -- Thiago Henrique www.adminlinux.com.br

good day! I'm experiencing problem with pop3 proxying: on backend servers in logs there's director's ip instead of remote's like this: Jun 8 15:21:23 host-01 dovecot: pop3-login: Login: user=<test1 at example.com>, method=PLAIN, rip=192.168.5.102, lip=192.168.5.100, mpid=26170, secured Jun 8 15:32:16 host-01 dovecot: pop3-login: Login: user=<test1 at example.com>,

As someone who is about to begin the process of moving from maildir to mdbox on NFS (and therefore just about to start the 'director-ization' of everything) for ~6.5m mailboxes, I'm curious if anyone can share any experiences with it. The list is surprisingly quiet about this subject, and articles on google are mainly just about setting director up. I've yet to stumble across an

Hello, I have discovered a strange behaviour with director proxying... I have a user, its assigned server is 155.54.211.164. The problem is that I don't know why director sent him yesterday to a different server, because my server was up all the time. Moreover, I'm using poolmon in director servers to check availability of final servers and it didn't report any problem with the

Hi, I have a director farm running in front of dovecot pop/imap servers. For a reason, one of my backend servers have been down, so poolmon disables it in director servers and users corresponding to it has been sent to other servers. Until this, no problem. Now my failed backend server is up again, and I want to redirect all of its users to it, without waiting for it director sessions to

Hi, i have short question for automatic failover, directors <-> backends is this still the way to go? -> https://dovecot.org/pipermail/dovecot/2012-October/138816.html https://github.com/brandond/poolmon -- Mit freundlichen Gr??en / best regards Markus Raps

I'm working the kinks of a new director based setup for the eventual migration away from courier. At this point, with everything basically working I'm trying to ensure that things are properly monitored and I've run into an issue. There doesn't appear to be a way to get dovecot to tell if it is (or is not) connected and properly synced with the other director servers in the ring

I have Poolmon (https://github.com/brandond/poolmon) set up. When it does all the checks concurrently, obviously there are locking issues on each mailserver it tests: "Warning: Locking transaction log file xxxx/indexes/dovecot.list.index.log took 60 seconds (syncing)" It's just an empty mailbox. Is there any way to do a login test, without locking the index files? Hence

I've been planning to improve poolmon failure checking for a long time already, but I still haven't managed to get to it. Maybe somebody else has more time, so here's a feature request for anyone to implement: poolmon currently gives up immediately if the first check to any service fails. It really should be trying multiple times over multiple seconds before giving up. I think ideally

Hi all. I'm writing a director health checker and ask you for suggestions. My project repository: https://github.com/duderamos/dovesitter Thanks.

Hi My servers are Ubuntu 14.04 and I'm needing to make a Upstart script for Poolmon. Does someone already made this and could to share with us ? Thanks! -- Thiago henrique
