I configured libre with a DB server, a web server with nginx, the memcached and RRDCACHED service (for images) and two pollers. I have a problem related to the cluster system (distributed poller) and I have read that I should use either the REDIS or the MEMCACHED is correct? I set using the MEMCACHED in the .env file only the entry CACHE_DRIVER = memcached, then in the config.php of the pollers I configured: $ config [‘distributed_poller’] = true;
$ config [‘distributed_poller_name’] = php_uname (‘n’);
$ config [‘distributed_poller_memcached_host’] = “x.x.x.x”;
$ config [‘distributed_poller_memcached_port’] = 11211;
The problem is that the system sees me as a cluster master server but I have a message that says “device unpolled”. If I debug with ./validate.php
[WARN] Using memcached for distributed locking, you should set CACHE_DRIVER = redis
[FAIL] Dispatcher service has not reported stats within the last poller window
Can someone explain to me if it is true that I have to use MEMCACHED as an alternative to REDIS and if my configurations are correct and why the devices are no longer monitored?
Thanks
