Logging not working
Hello!
Okay, so I'm trying to get the logging to work. Your CGI scripts, such as "startlog" uses the command "varnishlog -D -c -m ReqStart:$REMOTE_ADDR -w /var/rsvp/www/logs/$REMOTE_ADDR.log".
For me $REMOTE_ADDR seems to be empty, so the command doesn't do anything because it's now just "varnishlog -D -c -m ReqStart: -w /var/www/rsvp/www/logs/.log"
What am I missing?
That's weird. $REMOTE_ADDR is used so that you get only the log for you own requests. If you remove it it will work but you'll get all requests.
Hmmm... so is $REMOTE_ADDR a fairly standard variable on linux systems? Where does it get set?
It's a cgi environment variable. It is set by Apache. (It won't work if you run the script from a terminal)
Yeah, that was confusing me. I thought it might be Apache related.
I just added a quick test CGI script (my first!) to output some variables. This was the output:
SERVER_SOFTWARE = Apache/2.2.22 (Ubuntu) SERVER_NAME = rsvp.vm GATEWAY_INTERFACE = CGI/1.1 SERVER_PROTOCOL = HTTP/1.1 SERVER_PORT = 8989 REQUEST_METHOD = GET HTTP_ACCEPT = text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 PATH_INFO = PATH_TRANSLATED = SCRIPT_NAME = /cgi-bin/test.bat QUERY_STRING = REMOTE_HOST = REMOTE_ADDR = 192.168.80.1 REMOTE_USER = AUTH_TYPE = CONTENT_TYPE = CONTENT_LENGTH =
REMOTE_ADDR is there although other variables aren't but hopefully they aren't important.
So I re-ran the command from the command line with the remote address substituted in: varnishlog -D -c -m ReqStart:192.168.80.1 -w /var/rsvp/www/logs/192.168.80.1.log
... and nothing happens. I check to see if a varnishlog process is running (ps aux | grep varnishlog) but nothing is running.
I tried simply running "varnishlog" to start a log running from the command line and it definitely works.
Any ideas?
FYI I tested running "varnishlog -c -m ReqStart:192.168.80.1" and it worked as expected - only showing log information when I browsed my target website that gets served via Varnish.
Good idea, check the error logs... facepalm

I'm afraid I'm still at a loss as to why this isn't working. Did you ever manage to look in to this at all?
