Need to take the code used on the detail pages to auto-refresh the graphs and bring it over to the hosts page. The aggressiveness value on the host page should probably be a different one then the detail page since a host page might list dozens of graphs.

(Depends on jQuery in order to work.)

Prior to coding the snmp-fix branch, interface traffic graphs showed recived/sent bytes/packets with one graph above the zero axis and the other graph below the zero axis.

This bug probably also affects any disk graphs.

Need to fix graph generation to display the old-style graphs with xmit/recv above/below the y-axis zero point.

Add a text box which can be used to quickly filter the list of graphs in a particular which are displayed. The best approach will probably be to create and assign multiple classes to each div or img on the page. One class for the p= argument, one for the t= argument and one for the pi=argument.

Possibly include checkboxes which control whether the p=, t= or pi= arguments are searched.

Will require the use of jQuery.

The refresh rate of the graph on the detail page should be calculated on the fly based on an aggressiveness value in the config file along with a true/false flag for turning on auto-refresh.

The aggressiveness value should be range 1..1000, with higher numbers resulting in faster refresh rates. The number of seconds between refreshes can be calculated as (graph width) / (aggressiveness). A default of 200 for the aggressiveness value will probably be fine.

86400 / 200 = 432 seconds between refreshes
7200 / 200 = 36 seconds
28800 / 200 = 144 seconds

For a 1 hour graph (3600 sec), the maximum refresh rate would be 3.6 seconds.

In collectd 5.3, the df plugin creates (2) sets of files. One is prefixed with "df_complex" the other is prefixed with "df_inodes" (created by "ReportInodes true" setting).

CGP displays both of these as "Free space (device-name)" in the graph headers and uses "Bytes" as the Y-axis label on both. The inodes chart needs to have the y-axis changed and the graph title changed.

Sample filenames:

df_complex-free.rrd
df_complex-reserved.rrd
df_complex-used.rrd
df_inodes-free.rrd
df_inodes-reserved.rrd
df_inodes-used.rrd

CGP cannot graph RRD files for the snmp plugin which have complex filenames (spaces and other characters).

Sample filenames (from different devices, parent directory is always snmp):

Possibly confused by the configuration of the snmp plugin:

<Data "traffic">
# The total number of octets received on the interface,
# including framing characters.
Type "if_octets"
Table true
InstancePrefix "traffic-"
Instance "IF-MIB::ifDescr"
Values "IF-MIB::ifInOctets" "IF-MIB::ifOutOctets"

Except that the following devices does at least graph the traffic correctly:

if_octets-traffic-HP ETHERNET MULTI-ENVIRONMENT,ROM G.07.02,JETDIRECT,JD3.rrd
if_packets-packets-discards-HP ETHERNET MULTI-ENVIRONMENT,ROM G.07.02,JETD.rrd

if_packets-packets-multicast-HP ETHERNET MULTI-ENVIRONMENT,ROM G.07.02,JET.rrd
if_packets-packets-unicast-HP ETHERNET MULTI-ENVIRONMENT,ROM G.07.02,JETDI.rrd

If the network plugin is configured with "ReportStats true", then it creates RRD files named:

if_octets.rrd
if_packets.rrd
queue_length.rrd
total_values-dispatch-accepted.rrd
total_values-dispatch-rejected.rrd
total_values-send-accepted.rrd
total_values-send-rejected.rrd

CGP does not support the network plugin.

Need to improve how CGP looks when it is printed. Specifically, hiding some of the divs which are used for navigation along the left side.
