Graphing SNMP String with Weathermap

[Atreides]

Hello,
I'm trying to display a snmp string on weathermap but cant figure it out exactly, what should the LABEL be.

NODE MODULE_TYPE
LABEL {node:this:snmp_out_raw}
LABELFONT 113
LABELOUTLINECOLOR none
LABELBGCOLOR none
TARGET snmp:{map:community}:172.25.232.33:1.3.6.1.2.1.47.1.1.1.1.2.1044
USESCALE CHANGE
POSITION 200 200

snmpwalk -v2c -c test 172.25.232.1 1.3.6.1.2.1.47.1.1.1.1.2.1044
SNMPv2-SMI::mib-2.47.1.1.1.1.2.1044 = STRING: "1000BaseBX10D Gi1/3"

I want go graph the "1000BaseBX10D" part.

Log from weathermap :

ProcessTargets: NODE MODULE_TYPE, target: snmp:{map:community}:172.25.232.33:1.3.6.1.2.1.47.1.1.1.1.2.1044 on config line 902 of /var/www/html/cacti/plugins/weathermap/configs/test was not recognised as a valid TARGET [WMWARN08]

You need to specify an OID for the in and out values, even if you aren't using them. Since you are using 'out' in the label, your TARGET should be:

Code: Select all

TARGET snmp:{map:community}:172.25.232.33:-:1.3.6.1.2.1.47.1.1.1.1.2.1044

To say that you don't care about the in value (the extra '-' in the middle).

Also, Weathermap currently only supports SNMPv1 - 2c & 3 should be in the next version. It's written but not yet tested. It should work with 0.98 if you feel brave: https://github.com/howardjones/network- ... nmpv2c.php. You would need to change the target to snmp2c: instead of snmp:

[Atreides]

Great, thank you Howie.

[Howie]

Just a quick follow-up. I just tested with 0.98 version and the SNMP2c plugin from github, and that works as expected:

Code: Select all

WIDTH 400
HEIGHT 400

NODE n1
   POSITION 200 200
   TARGET snmp2c:public:127.0.0.1:.1.3.6.1.2.1.1.7.0:.1.3.6.1.2.1.1.6.0
	LABEL {node:this:snmp_out_raw}

Hi,
Not quite related to weathermap or maybe....
I'm trying to graph some values from my layer3 switch :

Optical Optical
Temperature Voltage Current Tx Power Rx Power
Port (Celsius) (Volts) (mA) (dBm) (dBm)
---------- ----------- ------- -------- -------- --------
Gi1/1 25.0 3.34 5.9 -6.4 -12.2

snmpwalk returns those values, but its missing a dot :

[root@msq ~]# snmpwalk -v2c -c test 172.25.232.33 1.3.6.1.4.1.9.9.91.1.1.1.1.4.1022
SNMPv2-SMI::enterprises.9.9.91.1.1.1.1.4.1022 = INTEGER: 33
[root@msq ~]# snmpwalk -v2c -c test 172.25.232.33 1.3.6.1.4.1.9.9.91.1.1.1.1.4.1023
SNMPv2-SMI::enterprises.9.9.91.1.1.1.1.4.1023 = INTEGER: 59
[root@msq ~]# snmpwalk -v2c -c test 172.25.232.33 1.3.6.1.4.1.9.9.91.1.1.1.1.4.1024
SNMPv2-SMI::enterprises.9.9.91.1.1.1.1.4.1024 = INTEGER: -65

How can I insert a "." between my values ?

[Howie]

Code: Select all

TARGET 0.1*snmp2c:test:172.25.232.33:1.3.6.1.4.1.9.9.91.1.1.1.1.4.1022:-

[Howie]

Code: Select all

TARGET 0.1*snmp2c:test:172.25.232.33:1.3.6.1.4.1.9.9.91.1.1.1.1.4.1022:-

If it's for a Cacti graph, you use CDEFs to do this.

[Atreides]

Tried snmp2c but no joy so far, am I missing something ?

[Howie]

No, that looks right. If the format is wrong, you get the "not recognised as a valid TARGET" message. This is the snmp2c plugin saying that it couldn't fetch data, so that means it was loaded, and did recognise the target as a valid formatted one.

Things I'd try:

1) Try without the 0.1* just in case (this shouldn't make any difference, but lets solve one thing at a time )

2) Try with a . on the front of the OID - technically it's not formatted correctly without one, but most things don't care.

3) Try with debug logging? You'll get more information about what's going on inside the snmp plugin (grep for 'ReadData' lines)

[Atreides]

Tried first all points on your list .

Weird is, on another machine with version 0.97 and snmp v1 its working(with 0.1*snmp:test:172.25.232.33).

I tried even with snmp v1 , same result. Same conf(snmpv1) on 0.97 is working properly and displaying what I want.

[Howie]

That's interesting! I'll see if I can add some more logging.

What's the device? Anything unusual?

[Atreides]

No, its a Cisco 6500 Multilayer Switch.

[Howie]

OK, well those definitely work for me I haven't tried with 0.98 on our own prod yet though

I decided to write in this thread.
I have 5 ups in 2 DC and I want to build weathermap with all 5 ups showing important parameters.

I started from one of them:

Code: Select all

	POSITION node_ups1_zop_co1 0 25

	POSITION node_ups1_zop_co1 0 50

NODE node_ups1_zop_vi1
	LABEL U1(in):{node:this:snmp_in_raw}V
	NOTES Napiecie wejsciowe 1
	LABELOUTLINECOLOR none

	TARGET snmp:public:10.32.69.2:.1.3.6.1.4.1.4555.1.1.5.1.3.3.1.2.0.0:-
	USESCALE none in percent
	POSITION node_ups1_zop_co1 0 75

and so on.

It doesn't looks good, but it works well. Later I'll present the data in a table.
I wanted to show ups status too.
UPS website interface presents dynamic visualisation of status. Look at the attachment.

I made 5 pngs: ups_status_1.png, ups_status_2.png, ups_status_3.png, ups_status_4.png and ups_status_.png.
It doesn't work. Weathermap displays ups_status_.png not ups_status_3.png which refers to actual value.

What is wrong, where is the bug?

[Howie]

inscaletag refers to the text after the colour, on the scale lines. You don't have that, so it's an empty string.

Code: Select all

SCALE UPSSTATUS 1.6  2.5   163   1  82  2

would be one way to fix that. You may as well use the word 'none' at that point, to make it easier to understand what is going on though, or even the name of the png file in its entirety.

Code: Select all

SCALE UPSSTATUS 1.6  2.5   163   1  82 ups_status_none.png

NODE xx
    ICON images/{node:this:inscaletag}
