On doc https://docs.librenms.org/#Extensions/Distributed-Poller/, the set up in the sample is
1 Web / API server
1 DB server
1 RRD Storage server
3 Pollers
where memcached service is running on the DB server.
On doc http://librenms-master.readthedocs.io/Extensions/Memcached/, it states “If you use the Distributed Poller, you can point this to the same memcached instance. However a local memcached will perform better in any case.”
Question:
To get better performance, in this sample case, is it valid to install memcached on the following servers locally?
1 Web / API server
3 Pollers
with the config like
Memcached
$config[‘memcached’][‘enable’] = true;
$config[‘memcached’][‘host’] = “localhost”;
$config[‘memcached’][‘port’] = 11211;
on these servers
