</div>The problem I have is I want TONS of graphs. I want to graph our load<br>
balancer, our firewall, our CPU usage for specific processes across<br>
servers (apache, memcache, mysql, etc.), memory usage (free/available),<br>
mysql statistics (threads running, queries running, long running queries,<br>
average query time, seconds behind master, etc.), and much much more. If<br>
I have all of these statistics being reported (and graphed), then is this<br>
something that reliably, a pull method can perform well? I've used SNMP a<br>
lot to gather basic statistics, but I doubt I'd be able to get SNMP to<br>
broadcast what the current queries per second are on the local MySQL<br>
server easily (I know its possible - there's an SNMP module for MySQL, but<br>
I doubt its trivial). Wouldn't something like this be better as a script<br>
running on ALL servers to gather the statistics and push those statistics<br>
to a centralized daemon of sorts running on the server?<br>
<br>
But since I also need to graph things that are snmp-based (for instance,<br>
our load balancer information can only be obtained via snmp), my thoughts<br>
are that using cacti is most likely the best option, but I'd have to use<br>
the custom-graph-with-scripts option more often. Or, like I asked,<br>
perhaps using ganglia to push the statistics, and then running a script on<br>
the cacti server to convert the ganglia data into graphs?<br>
