Greetings to all. First, a hearty thank-you to Javier and all of the other developers/contributors that have made JFFNMS such a useful and robust tool. Each of my previous three employers has been highly impressed with the capability and utility of JFFNMS. JFFNMS and Cacti have become my go-to tools for managing availability and performance of all hosts that I am responsible for (even when more expensive commercial tools are readily available).
On to my woes:
I am using 0.8.5 (with rrdtool v1.4.3-1) on Ubuntu Server 10.10 to monitor
a mixed bag of physical servers and VMware (guest) hosts, and I am having
some interesting issues. I've checked the archives carefully, but have
been unable to resolve these issues on my own.
1.) I have no Traffic graphs on any host (The RRDTool files for Interface
ID 72 (from Host ID 4), has not been created by the Poller Process yet).
I'm running 0.8.5, so the backslash\colon bug is not in play here.
2.) Network interface utilization on all guests (all Server 2003 R2, some
hardware, some VMs) shows '0%'. There is a blue line on the graph ('Output
Utilization') at 0%. There are no error messages.
3.) RTT & Packet Loss on all guests shows '0%'. There is a graph, but it
is bare (no lines). Strangely, there is a 'The RRDTool files for Interface
ID 84 (from Host ID 5), has not been created by the Poller Process yet')
message below the graph.
4.) Physical Memory 'total storage' value is detected incorrectly on every
host with > 4GB RAM. The higher the installed physical RAM, the greater
the error, it seems. See attached screen shots. Occasionally, the 'used
storage max' value' exceeds the value of the physical RAM, as well. There
is no 'total storage' line visible, except at the far end of the graph.
I've used JFFNMS previously (0.8.4 or 0.8.3, I believe), and had no
issues, but then, I was not monitoring VMs, nor hosts with much more that
2-4GB installed RAM.
My current implementation is a proof-of-concept for the big shots, and I'd
like to get these issues solved (or at least understand the current
limitations) before I seek final approval to install in production.
I'd be grateful for any assistance or further clues.
