Collectd, the backbone of Luci statistics module, has been recently updated
already to 5.4.0, while Openwrt is still with 4.10.8.
5.0-5.4 branches have been released in 2011-2013 and the last Collectd
release in August 2013 only contained 5.3 and 5.4.
Although 4.10.x is still marked as supported, it is said to be being "phased
out" and no new commits have been made for a while.
My ar71xx/wndr3700 build has been using 5.2.1 since February (see
http://patchwork.openwrt.org/patch/3299/ and
http://patchwork.openwrt.org/patch/3300/ ).
I have now bumped up the version to 5.3.1 and have refreshed the needed patches.
I have compile-tested (with ar71xx) all collectd modules, and I have verified
the real-life functionality of the following plugins: Conntrack,
CPU/Processor, DNS, Interfaces, Memory, Netlink, Ping, Processes, TCP
Connections, System Load, Uptime, Wireless.
The version bump requires changes both to collectd in the packages feed and
to Luci sources, as some of the data items have changed name or file
structure. Both need to be patched at the same time.
I am including two separate patches:
one for collectd in packages and one for luci-statistics in Luci trunk.
Explanation of main patches for collectd in packages feed:
- 140-fix-fqdnlookup.patch : FQDNLookup option has been turned on by default
since 5.1. If that option is enabled, it causes collectd to refuse to start
in a basic Openwrt box as typically a fully qualified domain name does not
exist for the router. (That error related can only be properly seen when
console is used to start collectd. Otherwise Luci statistics collectd simply
dies immediately after starting it.) That option should be false by default.
I included a new patch 140-fix-fqdnlookup.patch to turn the option off by
default.

- quilt choked on some -Werror related patches, so I removed them from
003-remove-werror.patch.
- 120-fix_kernel_2.6.37.patch seems to be unnecessary as the file to be
patched has been removed. Removed.
- 130-timeleft-max.patch is included upstream. I removed it.

- 105-rrdtool-csv-honor-datadir-531upstream.patch is needed to correct a rrd
file path bug in 5.3.1. Already fixed in upstream.

Regarding data presentation in Luci-statistics, there are three changes
requiring patches to Luci feed:
-conntrack result data has changed name from "entropy" to "value".
-ping result data has changed name from "ping" to "value".

-interface plugin has changed rrd data file structure so that the plugin
instances (=interfaces) have separate data files. Luci needs to draw the
graph for each plugin instance, not for each data instance.
