CactiEZ v0.7 and Weathermaps 0.97a

[duyenngv]

I have installed CactiEZ v0.7 on VMware Workstation v9.0:
Plugin Management (Cacti Version: 0.8.8a, Plugin Architecture Version: 3.1) and Weathermaps 0.97a

I work with Weathermaps to monitor network connection status.
I draw map and config Weathermaps: if the connection is up the link would be green and if the connection is down the link would be red.
"Poller Interval" and "Cron Interval" are " Every minute"
I also use "Monitor" and "Thold" to get warning email.

If a device shutdown, I get email warning after 2 minutes and Weathermaps change (link on the map) to red after 12 minutes

If the device up after shutdown, I get email warning after 3 minutes and Weathermaps change (link on the map) to green after 3 minutes

So it is OK if device up after shutdown. Its not good when device shutdown, it take too long time to change link status.
Have you got the same problem ?

I see Weathermaps 0.97c now, I try to upgrade Weathermaps by use them command " yum update" in console
but I dont see change int Weathermaps plugin, it seem upgrade OS.
How can I upgrade Weathermaps 0.97c plugin from Weathermaps 0.97a?
thank you
Sorry for my English

[Howie]

How did you configure weathermap to detect links being down? Please paste the config for a link.

To upgrade, unzip the new version over the top of the old version, in cacti/plugins/weathermap (I don't know where that folder is on CactiEZ)

@Howie:
The config for a link ( link include two interface, if device up -> interface up -> green and vice verses)
LINK node02318-node02287
INFOURL /graph.php?rra_id=all&local_graph_id=153

and the color for link:

About upgrade, I upgrade it by using Winscp: delete weathermap folder, copy new one, copy editor.php from old one, change folder permission. When I done, I can see map but I cant edit map
I get error like this:
Warning: require_once(Weathermap.class.php): failed to open stream: No such file or directory
in /var/www/html/plugins/weathermap/editor.php on line 4 Fatal error: require_once(): Failed opening
required 'Weathermap.class.php' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/plugins/weathermap/editor.php on line 4

Thank you

[Howie]

why did you copy editor.php from the old install? You can't use part of one version and part of another...

When I use all new file, I got some errors, I read somewhere to recommand use the old one.
have you got idea about the time of link ?

[Howie]

Yes, it sounds like RRDtool averaging.

Cacti doesn't look at the data on the link to decide if a device is down. Weathermap is looking at the traffic on the link. RRDtool works by averaging over time, so it will take at least 2 poller cycle to show exactly zero - the first one will be "half full" so not zero.

Did you start with 1 minute polling, or did you change later? If you changed after the graphs were created, then the graphs would still have 5 minute average values inside them.

Those two things together explain the 'lag'.

If you just want to have a link go red when the device is down in Cacti, use the cactihost: TARGET instead. Then Weathermap and Cacti will behave the same.

[duyenngv]

@Howie

I start with Poller 1 minute and cron 1 minutes
It get lag only when device changes from up to down

[Howie]

You will still get better results using the cactihost target.

[duyenngv]

thank for quick reply,
If I change TARGET as cactihost ( Ping - Advance of device), I will lost link status as red or green.

[Howie]

I thought you wanted to monitor the HOST status?

[duyenngv]

I thought you wanted to monitor the HOST status?

If I only want to monitor host status, I will use "monitor" plugin.

[Howie]

Then you should probably look at monitoring ifOperStatus for the interface, rather than traffic. This is the actual up/down state of the interface on the router.

If you use the snmp target in Weathermap, then this is queried directly from the router. For example:

Code: Select all

SET community public

LINK connection1
    SET ip 10.1.1.2
    SET interface 23
    TARGET snmp:{map:community}:{link:this:ip}:.1.3.6.1.2.1.2.2.1.8.{link:this:interface}:-

You will need to get the snmp interface number from 'verbose query' in the Cacti device menu.

Then 1=up, 2=down and 0=unknown/failure

Hi Howie,

I am new to Cacti and Weathermap (experience wise). What you have described here is EXACTLY what I am looking for. However, I don't really understand how to write this into a config.

Below I have copied and pasted a part of a live config on our network (from the links section not the nodes section).

Code: Select all

LINK V100R1-27kswitch
	INFOURL /graph.php?rra_id=all&local_graph_id=217
	OVERLIBGRAPH /graph_image.php?local_graph_id=217&rra_id=0&graph_nolegend=true&graph_height=100&graph_width=300
	TARGET /var/www/html/rra/draytek_v100_r1_traffic_in_219.rrd
	NODES V100R1 27kswitch

In my example would I keep the
"V100R1-27kswitch" as is, as this simply represents the name

Then delete all the rest and replace as follows

SET ip "IP of switch"
SET interface "port on switch"
TARGET (I don't understand how to build this line)

Assuming everything here looks correct. Could you explain how to correctly write the TARGET line. What info I should enter here and where I need to get that from.

Thanks in advance for any assistance you can give.

Hi Guys,

I am trying to figure out how to monitor the status of links on our network. I have created a test map with only one link in it.

The idea as suggested above is to monitor the "ifOperStatus" of the ethernet port on the switches.

Currently, the best I can get is that it always says the link is down.

Below is the code I have used for the map and below that is an SNMP walk of the switch in question. The port im interested in on this example is port 4.

Thanks for any help anyone can provide.

Code: Select all

The line in my example was correct The whole point is that it pulls the details from those SET lines, so you don't have to change the TARGET for each port.

You also missed the "SET community...." line which belongs in the top section of the file, before any nodes or links.
