Link Status Information

[eshmam]

I able to generate host status (red, yellow, green) & link utilization status in bits through below configuration.

Code: Select all

# That's All Folks!

Can anybody guide me how to get link status information (up/down) either through link color (red/green) or through link label color.

TIA

[Howie]

Instead of traffic? You are already colouring the links for traffic.

The basic idea though is that you need a data source that tells weathermap the link state. All it ever does is turn numbers into colours.

So the two main options are:

1) Have cacti graph ifOperStatus for your interfaces - you'd need to get additional Cacti templates for this, and it would be averaged, the same as other rrd graphs. Then just use those new rrd files as TARGETs for your links.

2) Use SNMP in Weathermap directly to check the current state. This means that the weathermap config needs to have all your snmp credentials in it, and the IP for every host. TARGET would be snmp:........

Neither one is really great.

[eshmam]

Can you please elaborate the option 2 with an example. I am fairly new in weathermap.

Traffic based color coding is very useful. But for me more important is to get link status (up/down) from weathermap. If that could be achieved with traffic color coding that would be great. Can it be done through link label by keeping link traffic colors as it is ?

Another, not related question, but hopefully I can get answer on this thread. Currently I'm placing nodes through web editor. Can it be calculated the position values for numbers of devices so I can place the devices without help of web editor. Would appreciate any reference/example.

[Howie]

Part 2 first:

You don't need the editor for anything. An easy way to stack up nodes in a row is to position them relative to each other:

Code: Select all

NODE a1
  POSITION 100 100

# this node is 100 pixels to the right of a2
NODE a2
  POSITION a1 100 0

Now if you change the position of a1, the others (there can be many, each relative the the previous, or the first one) will follow it.


Part 1:

You can't change the colour of the bandwidth label according to value, only node background colour or link fill colour.

SNMP would look something like:

Code: Select all

SCALE ifstatus 0 1.5 255 0 0
SCALE ifstatus 1.5 2.5 0 255 0

LINK a-b
  NODES a b
  BANDWIDTH 100
  USESCALE ifstatus
  TARGET snmp:public:192.168.0.1:.1.3.6.1.2.1.2.2.1.8.88:- snmp:public:192.168.0.22:-:.1.3.6.1.2.1.2.2.1.8.44

So that is two separate targets on one line, with a space between. One is to get the interface status on one switch, and the other for the other end. So they have different IPs and can have different communities (instead of public). the OID ends in the interface number (44 or 88 here) which you should be able to see in Cacti in the data sources list. Also note that in the first one, it ends :- and in the second one, there's a :- in the middle, this is what makes the first value go to the 'in' side of the link, and the second value go to the 'out' side of the link.

The BANDWIDTH 100 makes it so that when weathermap calculates the percentage bandwidth, it'll be the same as the actual value (0,1,2,3,4,5) for numbers below 100. The ifstatus scale has entries for up and down, but there are often other states of ifOperStatus depending on your vendor. See SNMP docs for that - e.g. https://cric.grenoble.cnrs.fr/Administr ... .1.2.2.1.8

I able to create accordingly but need some help probably on scale configuration.

My devices are cisco (2=down, 1=up)

following snmpwalk result

Code: Select all

# snmpwalk -v 2c -c public  172.21.160.206  1.3.6.1.2.1.2.2.1.8.108
IF-MIB::ifOperStatus.108 = INTEGER: up(1)
# snmpwalk -v 2c -c public  172.21.188.41 .1.3.6.1.2.1.2.2.1.8.88
IF-MIB::ifOperStatus.88 = INTEGER: up(1)

and below is the configuration

Code: Select all

SCALE ifstatus 0    1.5  255   0   0
SCALE ifstatus 1.5  2.5    0 255   0

LINK 152-141_copy
        WIDTH 4
        NODES 152 141_copy
        BANDWIDTH 100
        USESCALE ifstatus
        TARGET snmp:public:172.21.188.41:.1.3.6.1.2.1.2.2.1.8.88:- snmp:public:172.21.160.206:-:.1.3.6.1.2.1.2.2.1.8.108

But the link always show red. My goal is up=green, down=red. how to achieve this ?

[Howie]

SCALE ifstatus 1.5 2.5 255 0 0
SCALE ifstatus 0.5 1.5 0 255 0

The scale was backwards, now 2 is red and 1 is green.

[eshmam]

Thanks a lot Howie. You are a lifesaver !

[Mednes]

Hi ! I have a cacti version 0.8.8f.
weathermap 0.97c.

I would like to do in the same page 2 links, 1 link with BWLABEL Bits and 1 link BWLABEL Percentage.
is it possible ?
thnx

[Howie]

Yes it is. You can set BWLABEL for a single link, or for the DEFAULT link.

[Mednes]

thank you.

and for inbound and outbound is what we can do just the max value ?. because by default it is the value current.

[Howie]

Look at INBWFORMAT and OUTBWFORMAT in the manual. You can also use this in either the DEFAULT or a specific link.

[Mednes]

can you show me an example ?

[Mednes]

I tried but it doesn't work . please give me an example

[Howie]

The example IN THE MANUAL is what you want...

[Mednes]

We need to change the current inbound and outbound value (default) to max
