1) Description of problem:

Calamri logs at /var/log/calamari/httpd_access.log show GET access calls going at two different time intervals.

The first GET request from graphite happens at every 60 seconds.

while the normal GET requests for other stats such as 'osd', 'server', 'pool', 'health', 'health_counters' etc.. is sent every 20 seconds.

It seems that the GET requests sent every 20 seconds may cause spurious traffic. Is there a specific reason for the GET requests to be sent every 20 seconds rather than the 60 seconds period?

2) Version-Release number of selected component (if applicable):

RHCS1.3.2

3) How reproducible:

Always

4) Steps to Reproduce:

a) Install a Calamari node.
b) Add the OSD and MON nodes to the Calamari interface
c) Watch the GET traffic going on from the Calamari node using :

# tailf /var/log/calamari/httpd_access.log
