Re: [Ganglia-general] ganglia web to monitor apache servers?

2016-01-03 Thread Aaron 
Peter,
Would the log tailer work for tomcat as well?
Would you recommend sflow over the log tailer?
Thanks!

Re: [Ganglia-general] ganglia web to monitor apache servers?

2015-12-31 Thread Peter Phaal 
You could use a combination of Host sFlow and mod-sflow on your Apache
web servers:
http://www.sflow.net/
https://github.com/sflow/mod-sflow

The following article describes how to configure the head-end gmond:
http://blog.sflow.com/2011/12/using-ganglia-to-monitor-web-farms.html

mod-sflow also exports Apache worker pool stats to Ganglia:
http://blog.sflow.com/2012/10/thread-pools.html

mod-sflow also exports URL, referrer, user-agent, response time and
status code information that you can use to derive metrics for each
web service. You could use sFlow-RT to calculate the derived metrics
and proxy them to gmetad:

Re: [Ganglia-general] ganglia web to monitor apache servers?

2015-12-31 Thread Peter Phaal 
Vladimir's blog has a solution that involves tailing the Apache log files:
http://vuksan.com/linux/ganglia/#Apache_Traffic_Stats

The sFlow protocol packs a large number of metrics in each UDP
datagram, so you should see a reduction in UDP datagrams per second
associated with monitoring. The C based mod-sflow / host-sflow agents
have a small memory and CPU footprint.

2015-12-31 Thread Aaron 
Thanks Peter.  Is there a way to use more a pure ganglia solution?  Will
sflow generate more udp traffic and/or cpu cycles?
