I have attached a small patch for the webfrontend that adds a gmond
started timestamp and uptime-style last reported time to the time &
string metrics on the host view. Included with this is a corrected
uptime function that properly formats the time string and adds seconds.
I also attached a simple patch to eliminate the following php warning
that I am seeing in my apache error log file:
[error] PHP Warning: Call-time pass-by-reference has been deprecated -
argument passed by value; If you would like to pass it by reference,
modify the declaration of fsockopen(). If you would like to enable
call-time pass-by-reference, you can set allow_call_time_pass_reference
to true in your INI file. However, future versions may not support this
any longer. in /home/www/ganglia.php on line 273
Finally, I have a small request. The webfrontend used to include
gmond_started & last_reported in the list of metrics that could be
selected in the cluster view for display/sorting. Although not really
metrics, this was sometimes useful. Could they be put back in? It
looks like the code was changed a lot when the gmetad query speedups
were added, which eliminated these from the list. I tried looking at
the code myself, but it looks like it would require modifying a lot of
the code and I am not a php expert.
