Improve the "power" of REGEXPs in Data Queries

[twelzy]

Hi everybody!

Many of the Graph Templates that I developed on my Cacti server had to use Script Queries.
That's because with SNMP Queries isn't possible to match more than one value in the <source> field, or because isn't possible to replace one (or more) matched value by another value in the <source> field!

I think that would be great if Cacti have some kind of "VALUE/REGEXP_REPLACE" option in the <source> field!
And it would be great too if using "VALUE/REGEXP" we have the possibility to match more than one value in the <source> field!

Thanks in advance!

May you please post an example?

Hi lvm!

Revisiting my post, I think that another kind of regexp would be a great addition: some kind of "VALUE/REGEXP" in the <oid_index_parse> field!

I work in a VERY BIG Telco/Service Provider in Brazil.
The ifAlias of (almost) all of our equipments is standardized with some mandatory and optional fields.
We need:

• - "VALUE/REGEXP" in the <oid_index_parse> field,
  - "VALUE/REGEXP" in the <source> field, with the possibility to match more than one value
  - "VALUE/REGEXP_REPLACE" in the <source> field, with the possibility to match and replace more than one value,

I will try to give you some examples:

Example 1: Internet Links in our Border Routers

We have 2 kinds of agreements in our Internet Links: transit and peering links.
And we classify these links in 2 categories: national and international links.
These classifications are shortened in the ifAlias as following:

• (TRANS|PEER)_(NAC|INTL)_.*

We have here 2 input fields: AGGREMENT and NATIONALITY.
So we need to match and replace:

• TRANS by Transit, in the AGGREMENT input field;
  PEER by Peering, in the AGGREMENT input field;
  NAC by National, in the NATIONALITY input field;
  INTL by International, in the NATIONALITY input field,

respectively!
In this case, we need a "VALUE/REGEXP_REPLACE" in the <source> field, with the possibility to match and replace more than one value!

And if we want to make a Data/Graph template that will list only these Internet links of our Border Routers, we need a "VALUE/REGEXP" in the <oid_index_parse> field, that matches only the ifAlias that begin with (TRANS|PEER)!

Thanks in advance!
