[ClusterLabs] crm_mon -h (writing to a html-file) not showing all desired information and having trouble with the -d option

[Lentes, Bernd]

Hi,

playing around with my cluster i always have a shell with crm_mon running because it provides me a lot of useful and current information concerning cluster, nodes, resources ...
Normally i have a "crm_mon -nrfRAL" running.
I'd like to have that output as a web page too.
So i tried the option -h.
I have crm_mon from pacemaker 1.1.12 on a SLES 11 SP4 box. I'm writing the file to /srv/www/hawk/public/crm_mon.html.
I have hawk running, so i don't need an extra webserver for that.

First, i was very astonished when i used the option -d (daemonize). Using that hawk does not find the html-file, although i see it in the fs, and it's looking good.
Hawk (or lighttpd) throws an error 404. Without -d lighttpd finds the files and presents it via browser !?!

This is the file without -d:

ha-idg-2:/srv/www/hawk/public # stat crm_mon.html
  File: `crm_mon.html'
  Size: 1963            Blocks: 8          IO Block: 4096   regular file

Same file with crm_mon -d:

ha-idg-2:/srv/www/hawk/public # stat crm_mon.html
  File: `crm_mon.html'
  Size: 1963            Blocks: 8          IO Block: 4096   regular file

I see no important difference, just the different inode.

This is the access.log from lighttpd:

10.35.34.70 ha-idg-2:7630 - [08/May/2017:18:04:10 +0200] "GET /crm_mon.html HTTP/1.1" 200 563 "https://ha-idg-2:7630/crm_mon.html" "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safa

It simply changes from http status code 200 to 404. Why ? 

And using "crm_mon -nfrotRALV -h /srv/www/hawk/public/crm_mon.html" i get the following output:

I'm missing the constraints, operations and timing details. How can i get them ?
