neteler · December 4, 2013, 10:34pm

Hi SAC,

munin cries for some days about

osgeo.org :: webextra.osgeo.org :: Load average
CRITICALs: load is 80.87 (outside range [:25]).

Does anyone have an idea why mapserver is “superactive” on webextra:

That's Martin's baby, vmap0 used by flightgear etc... the one we round
robin dns with hyperquad or some other machine.

I didn't realize that was another MapServer instance. Could someone
include details of this MapServer instance on the WebExtraVM page?

It's the last entry on the page:
http://wiki.osgeo.org/wiki/WebExtraVM#vmap0.tiles.osgeo.org

Guess it doesn't explicitly explain that it is mapserver.

Well .... It's me who's been re-activating Munin as well as the VMap0
web map service after the upgrade, but actually I just ported previous
configurations with no change. The Wiki entry at:

http://wiki.osgeo.org/wiki/WebExtraVM#vmap0.tiles.osgeo.org

still represents the current state of affairs.

Cheers,
Martin.
