ConfD Performance

General

Hello,

I would like to know if following stats for possible:

  1. Total Read/Write transactions occured.
  2. Ongoing transaction count.

In top output I saw sometime confd consuming more then 90% memory. I would like to plot its relation with transactions.

To run a test and get the current memory use stats and high watermark you could simply (Linux) do something like:

$ cat example.sh 
#!/bin/bash
for ((N=0; N <= 1000; N+=1)); do
    netconf-console --edit-config=my-merge-edit-config.xml &> /dev/null
    netconf-console --get-config -x /myconfig &> /dev/null
    netconf-console --get -x /mydata &> /dev/null
    netconf-console --edit-config=my-delete-edit-config.xml &> /dev/null
done
echo "---Memory high watermark and current use stats from /proc/<confd-pid>/status"
pid=`pidof confd`
result=$(cat /proc/$pid/status | grep -A 1 VmHWM)
echo $result;

If you would rather collect your own stats by receiving events from ConfD, you can for example listen to NETCONF log messages. See confd_lib_events(3) man page for details and the “notifications” ConfD example:

$ pwd
/Users/tailf/confd-6.4.3/examples.confd/misc/notifications
$ ./confd_notifications -N
TRACE Connected (maapi) to ConfD
TRACE MAAPI_LOAD_NS_LIST
TRACE MAAPI_LOAD_HASH_DB

ok Thanks… Yes this is possible…

I was expecting something like “./confd --transaction_count” kind of command… Please let me know in case such thing is feasible.
