Hello,
can anyone post a link to the syntax for all the functions in The Dude?
I’m trying to solve a problem : between 2 switches I have multiple links (n X 1Gbps) and I want to sum all the IN bytes from all the interfaces for graphing purposes.
To aggregate the RX traffic on the links use the following code, it will aggregate interfaces 7 - 9.
round(rate(diff32(oid("1.3.6.1.2.1.2.2.1.10.7"))*8))+round(rate(diff32(oid("1.3.6.1.2.1.2.2.1.10.8"))*8))+round(rate(diff32(oid("1.3.6.1.2.1.2.2.1.10.9"))*8))
If you need to aggregate more than 3 links then keep adding the following code after another + symbol.
round(rate(diff32(oid("1.3.6.1.2.1.2.2.1.10.10"))*8))
Create a new data source with the code you have created and it will graph the aggregate RX of the links you have added in.
1.3.6.1.2.1.2.2.1.10.x will give you the RX of the port
1.3.6.1.2.1.2.2.1.16.x will give you the TX of the port
where x is the interface number.
Open Charts then click on the Data Source tab and create a data source as shown below…
Adjust the interval time and keep times to your needs.
If you want to also have the aggregate of the TX just create another Data Source and use the TX OID (1.3.6.1.2.1.2.2.1.16.x) rather than the RX OID and you can then create a chart with both of them visable.
Add a new chart and then add your two data sources as shown below.
@Chris, thanks alot.
As you indicated I’ve created a new data source with the following code :
rate(diff32(oid_raw("1.3.6.1.2.1.2.2.1.16.129", 5, 5, "172.16.50.1", "v1-public")))+
rate(diff32(oid_raw("1.3.6.1.2.1.2.2.1.16.134", 5, 5, "172.16.50.1", "v1-public")))+
rate(diff32(oid_raw("1.3.6.1.2.1.2.2.1.16.256", 5, 5, "172.16.50.1", "v1-public")))+
rate(diff32(oid_raw("1.3.6.1.2.1.2.2.1.16.262", 5, 5, "172.16.50.1", "v1-public")))
and a second one, for outbound traffic.
Very useful your indications.
I’m still at the very beginning level and the help is away from being very useful.
If someone can indicate a good tutorial for Dude … don’t hesitate.
No worries glad it is of help. I think the best place for you to start would be to read through the Dude wiki which is available from the Dude’s homepage. On top of that have a read through the Probe Thread that is a sticky topic in this forum. It will give you some good pointers for creating functions and probes which will then hopefully start you off and soon you’ll be creating mind blowing functions and probes of your own 
All the best and good luck.
