wcf_performance_notice
log event message to all configured log receivers, including
Memlog
. An
example of this log message is shown below:
2014-10-04 08:47:25 Info ALG 200142 wcf_performance_notice
algmod=http cache_size=88 cache_repl_per_sec=3 trans_per_sec=8 queue_len=7
in_transit=2 rtt=1 queue_delta_per_sec=1 server=10.1.0.10 srv_prec=primary
When enabling the performance log, one of the following frequencies must be chosen for how
often log generation occurs:
•
Every 5 seconds.
•
Every 10 seconds.
•
Every 30 seconds.
•
Every 60 seconds.
•
Every 300 seconds.
•
Every 600 seconds.
Each
wcf_performance_notice
log message contains the following fields:
•
cache_size
The size of the WCF cache which contains the most recent URLs looked up against the
external WCF database server.
•
trans_per_sec
The number of database queries being sent per second. URLs are not always sent singly.
NetDefendOS will send batches when there is more than one waiting for processing against
the database.
•
queue_len
The length of the queue of URLs awaiting processing by the external WCF database server.
•
in_transit
The number of URLs in the queue where a request has been sent to the WCF database server
but a reply has not yet been received.
•
rtt
The round-trip time for the last WCF database server lookup.
•
queue_delta_per_sec
This is the amount the queue of waiting requests increases or decreases per second.
•
server
The IPv4 address of the server performing the database lookup.
•
srv_prec
The precedence of the responding server. A server with a higher precedence may not have
responded to the request and the next lower precedence has been selected.
The last snapshot sent as a log message can also be viewed on a management console using the
NetDefendOS CLI command
httpalg -wcf
. Below is an example of the output from the command
and as shown there is additional information compared with the
wcf_performance_notice
log
event message.
