Request processors reply field with filtering

[Razhan Hameed]

Hi guys,

I wanna send new fields in the CCA-U when the last chunk of data is asked by the Diameter client.

How can I do this filtering? I know there "gt" and "lte" but I dont know how to use them. I would appreciate an explanation or a solution...

Regards,

[Dan Christian Bogos]

Hi Razhan,

You could test something like: *lte:*cgrep.MaxUsage:10 (I hope it
works without conversion).

Hey Dan, I actually did, but it didn't work, can you show me a good way to configure it?

[Dan Christian Bogos]

Razhan,

I thought I already did ;).

You can also try a filter like:
*lte:*cgrep.MaxUsage:10ns
This will enforce the units to compare against (10) as time.Duration
(internal unit we use for all Usage types).
As a tip to troubleshoot, I recommend adding *log flag to your
templates and playing with the filter to make sure it matches your
expectations.

Dan I am trying it in every possible way it doesn't really work,

I am testing it with the result code field here

{"tag": "ResultCode", "type": "*constant",

    "filters": ["*lte:*cgrep.MaxUsage{*duration_nanoseconds}:3ns"],

    "field_id": "Multiple-Services-Credit-Control.Result-Code",

    "value": "2001"},

Razhan,

Please add log to your template, capture ngrep coming from CGRateS and
diameter reply which you send to Cisco. Pack them (ngrep+syslog+.pcap
of diameter reply) together with your CGRateS configuration and send
them over (you can also send it privately).

Hey dan I send all the necessary files

[Dan Christian Bogos]

Hi Razhan,

Based on your trace the MaxUsage replied is:
'{"id":1,"result":{"Attributes":null,"MaxUsage":2},"error":null}' and
your filter is:
'{"tag": "ResultCode", "type": "*constant", "filters":
["*gt:*cgrep.MaxUsage{*duration_nanoseconds}:3"], "field_id":
"Multiple-Services-Credit-Control.Result-Code","value": "2001"}'

hence your ResultCode will never be added since the filter does not
match.

I don't see any issue with CGRateS in this case.

Hi Dan,

I changed it to zero like this

"filters": ["*gt:*cgrep.MaxUsage{*duration_nanoseconds}:0"],

but still this field will not appear in the response and the maxUsage is still 2

[Dan Christian Bogos]

Hi Razhan,

Would need again all the information (your final config, ngrep on 2012
- important, since you sent me .pcap, syslog).

Thanks,
DanB
