Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

In my access.log I see requests coming from 127.0.0.1 and retrieving server's "/" and then all of graphics and CSS referenced in it. This happens regularly, every 5 minutes.

I want to find out what, why and how runs wget like this.

I changed "referer" in /etc/wgetrc to verify it's local wget executable making these calls, it is. Couldn't find anything suspicious in crontab. The server is running munin-node. Could a munin plugin be doing this?

Oh, OK, it's Munin's http_loadtime plugin. It's a plugin to graph httpresponse time of a specific page. Defaults to using wget and grabbing "http://localhost/". Mystery solved :-)
