Node color changing depends on status.

citycat · Post by **citycat** » Thu Sep 28, 2017 1:37 pm

Hi,

I have 30 cisco routers that are monitored by the Cacti. I want to do implement node color changing, related to a node state (that's not new on this forum) but I have a problem with a node state that is always "unknown". For node state detection I use ICMP ping & SNMP Uptime. What can be the reason of the unknown state?

Map configuration:

SCALE cactiupdown 0 0.5 192 192 192 images/router_unknown.png
SCALE cactiupdown 0.5 1.5 255 0 0 images/router_down.png
SCALE cactiupdown 1.5 2.5 0 0 255 images/router_unknown.png
SCALE cactiupdown 2.5 3.5 0 255 0 images/router_up.png
SCALE cactiupdown 4.5 5.5 128 128 128 images/router_unknown.png

# cactiupdown statuses:
#0 Disable
#1 Down
#2 Recovering
#3 Up
#5 Unknow

# End of global section

# TEMPLATE-only NODEs:
NODE DEFAULT
LABEL {node:this:name}
USESCALE cactiupdown in
ICON 70 70 {node:this:inscaletag}
MAXVALUE 100

What state is the device actually in?

Your scale actually will show 'unknown' for Disabled and Recovering too...

I don't see any notice about nodes state in logs (logging level - debug) but I've just tried to delete one by one scale tags for Disabled, Recovering and Unknown and it looks like all nodes in disable state, so the SCALE cactiupdown 0 0.5 192 192 192 images/router_unknown.png works.

I meant just look in the Cacti 'Manage..Devices' page

You don't need to do any detective work...

According to Device page all routers have up status!

Howie · Post by **Howie** » Fri Sep 29, 2017 7:32 am

OK, so in your debug logs, look for lines with "ReadData" in them. This is the actual process fetching data from Cacti. You'll see lines that say something like "Returning (2,2)" or whatever the state is.

I don't see any ReadData stings in logs - there're only WEATHERMAP: Poller[0] DEBUG: [ProcessString@Weathermap.class.php strings.

Howie · Post by **Howie** » Fri Sep 29, 2017 11:14 am

Is that looking in the cacti log viewer, or actually grepping for ReadData?

If you have debug logging turned on and there is literally nothing in the logs but ProcessString lines, something is very wrong indeed.

I realise that something wrong - looks like Weathermap doesn't get node status.

I see the following for each node in logs:

Right, but the ReadData lines will tell you what data it IS getting.

Which version of weathermap on which version of Cacti is this, incidentally?

citycat · Post by **citycat** » Fri Sep 29, 2017 12:14 pm

Cacti Version: 0.8.8h, Plugin Architecture Version: 3.1
Weathermap 0.98

Howie, do you have any ideas how to deal with the problem?

Howie · Post by **Howie** » Mon Oct 02, 2017 11:08 am

If the only debug log messages you get are from ProcessString, your weathermap installation is broken somehow. I would delete it and re-install.

In /var/log/messages I see ReadData for links only:

Wait a sec... you posted the DEFAULT node back up there. Do the other nodes actually have a TARGET line?
