  • 1.  Aruba-CX: Syslog Filter does not work properly

    Posted May 19, 2023 11:50 AM

    Hello,

    I want to filter out the syslog messages for the hpe-restd

    on Aruba-CX 6100 (PL.10.10.1040), I configured the filter for one syslog server, but the messages are not being sent to any of the configured syslog servers anymore:

    logging filter no-Rest
        enable
         100 deny includes hpe-restd
         1000 permit
    
    logging 172.16.0.38 include-auditable-events filter no-Rest
    logging 172.16.2.193
    logging 172.16.2.195
    logging 172.19.2.11
    


    But on the other side, on Aruba-CX 8325 (GL.10.09.1040) even when I apply the filter to every Syslog Server the hpe-restd events still are transmitted to the syslog servers.
    I tried to change the regexp syntax, but without success:

    logging filter no-Rest
        enable
         100 deny includes hpe-restd
         101 deny includes hpe\-restd
         102 deny includes hpe-restd*
         1000 permit
    
    logging 172.16.0.38 vrf MGMT-Switches filter no-Rest
    logging 172.16.2.195 vrf MGMT-Switches filter no-Rest
    logging 172.19.2.11 vrf MGMT-Switches filter no-Rest
    


    Anyone any idea?

    Thanks and kind regards

    Robert

    push again

    logging filter no-Rest
        enable
         100 deny includes hpe-restd
         101 deny includes hpe\-restd
         102 deny includes hpe-restd*
         103 deny includes (hpe-restd)
         104 deny includes .*hpe-restd.*
         1000 permit
    logging 172.16.0.38 vrf MGMT-Switches filter no-Rest
    logging 172.16.2.195 vrf MGMT-Switches filter no-Rest
    logging 172.19.2.11 vrf MGMT-Switches filter no-Rest

    but syslog server still receives the syslog entries:

    The filter works on the syslog message. The daemon (hpe-restd) is not part of that. You probably can filter on the event id. In my setup, I see all API calls being logged under event ID 4667 or 4668. You can filter those out:

    logging filter event-noise
         10 deny event-id 4667-4668

    There is a nice video on this feature.

    Hello Herman,

    thanks for your response.

    In my case there at least 4 event ids (others than yours):
    2025-01-06T15:25:22.965182+01:00 vs-hvt-r04 hpe-restd[3959]: Event|4657|LOG_INFO|AMM|-|User xxxx logged out of REST session from x.x.x.x
    2025-01-06T15:25:22.925436+01:00 vs-hvt-r04 hpe-restd[3959]: Event|4608|LOG_INFO|AMM|-|Authorization allowed for user xxxx, for resource SessionMgmt, with action POST
    2025-01-06T15:25:07.999934+01:00 vs-hvt-r04 hpe-restd[3959]: Event|4655|LOG_INFO|AMM|-|User xxxxx logged in from 172.31.200.250 through REST session
    2025-01-06T15:25:07.997869+01:00 vs-hvt-r04 hpe-restd[3959]: Event|4602|LOG_INFO|AMM|-|Authentication succeeded for user xxxx in session vBm8MfAtQcz2iGyrrdJhvw==

    I would have preferred a one liner, but I will try.
    And I hope its the same id on all of my cx switches (6000,6100,6200,8325,8360)...

    Kind regards 

    Robert

    As shown in that video, you can use commas as well:

    deny event-id 4602,4608,4655,4657,4667-4668

    The event-id for a specific message is expected to be the same across all CX platforms.
