Rajith Attapattu edited comment on QPID-3902 at 6/12/12 12:07 AM: ------------------------------------------------------------------ (*) I echo Justin's comment about Network and Protocol instead of IO and AMQP. (*) For Protocol we should really have something like [Protocol][{PROTOCOL_NAME}-{VERSION}]... bcos we will mostly likely end up with supporting multiple protocol versions in the same broker. So it will be very useful to filter by a specific version. Ex. [Protocol][AMQP-0-10] (*) I also think that BROKER is too broad a category to be really useful. A lot of things are lumped in there. I'm not sure if the following is possible , but if you can have more granular categories for BROKER it might be more useful. Ex. QUEUEING -- for logs related in putting/pulling messages from queues, flow control etc.. ROUTING -- logs related to routing messages (would be more relevant going forward) SUBSCRIPTION -- logs related to subscription state (capacity, acks ..etc) (*) Another general category could be CONFIGURATION. Often times customers wants to see logs to verify if they've got the config right. It's really a separate category from any of the above. We currently don't have much here. was (Author: rajith): (*) I echo Justin's comment about Network and Protocol instead of IO and AMQP.

This is a proposal to add log categories to C++ Broker log messages. > h4. Problem Statement > There are difficulties working with C++ Broker logging when appplying a log > filter criterion. What precise FILTERTEXT can a user specify for: > {noformat} > --log-enable debug+:FILTERTEXT > {noformat} > Even after the fix from QPID-3891 it is not intuitive what to specify for a > FILTERTEXT and any useful filter requires detailed knowledge of the source > code. > h4. Proposal > A log category is a high-level classification of the nature of the logged > event that is not tied to a particular source module or code function name. > This log category would become the target for FILTERTEXT log filters. > The following list is the proposed log category definition. Each log category > name is followed by a list of source code directory names that would > generally produce logs using that log category. > ||Category||Source code directory|| > |Security| acl ssl gssapi sasl cyrus| > |Broker | broker| > |Management| agent console qmf| > |Amqp| amqp_0_10 framing| > |System| log sys types xml thread mutex fork pipe time ...| > |HA| cluster ha replication| > |Messaging| messaging client| > |Store| store| > |IO| tcp rdma AsynchIO socket epoll| > |Test| | > |Unspecified| | > There is no strict rule that a module produce only log entries of a specific > category. > The category would be inserted into each log message after the time of day > but before the message text. > {noformat} > 2012-03-06 16:55:38 [Management] SEND PackageInd > package=org.apache.qpid.broker to=schema.package > {noformat} > A user could then filter log messages by using the category names: > {noformat} > --log-enable debug+:Management > {noformat} > This scheme would have a number of benefits: > 1. On a per-message basis the filter comparisons would be using enumeration > values and not strings. > 2. The feature could be documented sensibly. > 3. Log files would be easier to interpret manually or by event management > systems. > The classifications could be phased in gradually. The current > QPID_LOG(LEVEL, MESSAGE) would produce [Unspecfied] events while the new > QPID_LOG_CAT(LEVEL, CATEGORY, MESSAGE) would produce events using an actual > category. > Similar additions are made for the QPID_MSG entries. -- This message is automatically generated by JIRA.
