Pinned topic supress events from specific clients

‏2010-01-19T12:43:01Z |
Probably this question was mentioned before, but i couldn't find it back so this time again:

We use an external loadbalancer to distribute the traffic between two XS40's.
We have probe's setup on the loadbalancer to probe on specific tcp ports.

However now we get every 30 seconds a lot of messages in the system log for events 0x80e00130, 0x806000ca and 0x80e00531.
These probes are used from only two source adresses.

So I like to supress the messages with specific Id's only from the two loadbalancer adresses.

I can supress the ID's but then do it for all source adresses, this is not suitable.
I can't use the IP filter because this only allows log entry's from specified ip address and I like to Supress them.

Any way to do this ??

    Checked inside MessageReference 3.8.0 documentation. Here is the explanation for each of the event codes -

    0x0806000ca (NOT 0x806000ca) "The SSL subsystem was unable to locate the peer’s X.509 certificate during protocol negotiation".
    0x080e00130 (NOT 0x80e00130) "An incoming SSL connection failed."
    0x080e00531 (NOT 0x80e00531) "The connection shown is being terminated"

    Are you sending traffic over SSL? If you are then seems like that DataPower SSL Proxy profile has not been correctly setup to perform a correct SSL negotiation with the client. You might want to fix the SSL configuration rather than suppressing the errors.

    We terminate SSL on XS40. But the traffic is being loadbalanced via an external loadbalancer. This loadbalancer is using healthprobes to see if the XS40's are still alive. The probe sets up a ssl connection and only looks if the SSL responds, no client cert is send. However you then get the mentioned errors everytime the loadbalancer does a healthcheck, this is about every 30 seconds.

    What I actually want is to suppress every error caused by a specific client ip source, in this case the loadbalancer addreses.

    Out of curiosity - Can't you change your SSL Proxy, which you are using for health probe, not to do client authentication? You can get rid of the Val Cred definition from the Crypto Profile (which is used by SSL Proxy) and that should take care of not authenticating the client. (Assuming that your "Always Request Client Authentication" is set to off state). In that case DataPower will not generate the error.

    Now to answer the question about how you can suppress certain events in the log specific to an IP. I can answer the suppress part - Assuming that you are using the default-log "Log Target", there is a "Event Filter (Tab)--> Event Suppression Filter" function in the Log Target definition. You can specify the event codes which you want to be suppressed there. Though I am not sure how will you narrow it down to specific IP. There is another tab on the Log Target definition, "IP Address Filters". Here you can specify the particular IPs for which log should be monitored. You want the functionality the other way around. That's why not sure how to deal with the IP situation.

    Hi,

    As of 3.7.3, there is the option to subscribe to a specific client IP, but unfortunately, you cannot filter an IP. You can filter the event codes entirely, but then you run the risk of missing legitimate events. It's a bit of a balancing act.

    Hope this helps.

    Did anyone get a solution to this, has the ability to supress a log entry based on the IP address been updated in a newer release of the firmware?

    On 3.8.2.x firmware Objects->Logging Configuration->Log Target

    IP Address Filters
    IP address filters allow only those log messages from specific IP addresses to be written to this log target.
    So you cannot suppress an IP address but add all IP addresses you are interested to get log entries for
    (which might be too much or not possible at all).

    So now that we are on v5 is this implemented yet? Why in the world wouldn't we be able to ignore an IP or a set of IPs from the logs. I have the same exact problem! Our load-balancer sends these probes causing errors every 5-15seconds. I am with a fairly large company so getting the network team to change the way their load-balancers work is not really an option. So right now my only option is to suppress the event and miss possible legitimate errors? Because it's the default system log, and you can't change the filesize or rotation #, so these errors fill up both log files.

    This is very annoying. I created an Request For Enhancement. Please vote for it at the following link:

    http://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=64904

     

    Headline:
    Log Target IP Address Filter - Allow Subscription AND Suppression Filters
     
     
    Description:
    This Request For Enhancement is to update the IP Filter tab on a Log Target in DataPower to allow us to subscribe or suppress specific IP addresses from being included in that particular Log Target. Today we can only create an IP address filter to allow only those log messages from specific IP addresses to be written to this log target. This is not adequate, we need to be able to exclude specific IP addresses.
     
     
    Use case:
    We have multiple DataPower appliances hosting the same service, and an IP Load Balancer is sending traffic to the appliances. The IP Load Balancer is constantly probing the port to make sure its available, and as a result the DataPower logs fill with useless noise. If we suppress that particular message, we might lose legitimate error log entries for things not related to the IP Load Balancer probing. We want to be able to suppress just the few IP addresses of the IP Load Balancers in our Log Target.
