Bug Description

We found our log files for our l3 agent growing huge. By huge, I mean 10s of GB a day on a single compute host. We have heavy security group testing going on at the moment.

I found that around 75% of the size of a 5GB log file was due to ~ 30,000 occurrences of a line relating to security groups that contains "Update port filter for ..." The ... there is about 90,000 characters of python blob serialized to a string and output to the log file.

I did not mean l3 agent. I meant our neutron plugin agent running on compute hosts.

    Quiet down a large log file heavy hitter.

    This line of code serialized the python structure for the device and throws it
    at the log file. The string is about 90K characters, isn't very useful and we
    found that it takes a very large amount of space in the log file causing them
    to grow very quickly and fill our log disk. This change extracts the device
    name (e.g. "tapcdc07af9-8a") and uses that in the log message.
