: is used to delimit fields in DEF: rrd instructions, so when it appears
in a filename it must be escaped using \.[1] This commit adds the
escaping.
I discovered the issue after configuring collectd-mod-ping to monitor an
IPv6 host (2001:19f0:5:727:5b56:205d:ff55:2208). Accessing
https://192.168.0.1/cgi-bin/luci/admin/statistics/graph/ping would cause
the following messages to be logged:
Wed Nov 14 23:04:33 2018 daemon.err uhttpd[30261]: ERROR: can't parse DEF '2ping_avg_raw=/tmp/rrd/openwrthost/ping/ping-2001:19f0:5:727:5b56:205d:ff55:2208.rrd:value:AVERAGE' -2

and the graphs would not display. After applying this commit, the
graphs display correctly and no messages are logged.

Some graph definitions rely on data not supported across all APC UPSes.
Due to recent upstream changes in collectd, the daemon no longer creates
a NaN-filled .rrd file corresponding to any missing UPS data. Depending
on the connected UPS, this may result in some "broken" graphs on the Luci
Statistics page since rrdtool cannot find the expected .rrd file.
Include the add_supported() function to determine the UPS data available
at runtime and update any definitions of graphs to include only supported
data. For example, the whole chart stack of AC input and output voltages
will normally be "broken" if the UPS only measures AC input voltage. With
these changes, the output voltage graph definition is stripped out,
allowing the chart to render.
Make consistent use of data types and instances in graph definitions. All
definitions now use the same format with the 'instances' key. Unnecessary
'types' and 'sources' keys are removed.
Fix the definition of 'line frequency' graph, based on upstream collectd
apcups plugin code: type is 'frequency' but instance should be 'input'.
This also includes some code and whitespace cleanup.

The Voltage graph combines Battery, Input Voltage and Output Voltage.
The Y-Axis scale masks changes in Input/Output voltages over time.
This patch splits the graphs into 2 graphs.
This makes it possible to see variations in AC Input/Output voltages.

OpenWRT/LEDE support for APC UPSes is only partial: although the collectd
apcups plugin is included, related lua/luci code is missing. These changes
add the lua side and have been used for ~2 years, both on OpenWRT and LEDE.
Reworked from patches submitted by James Klaas to the luci development list
in 2015.

A missing or faulty luci_statistics config file may prevent
LuCI access completely already at the login phase as
the statistics config is parsed already then.
The error is like:
.../statistics/datatree.lua:16: attempt to index upvalue 'sections' (a nil value)
User may be completely locked out of LuCI until he figures out
the need to have a proper luci_statistics config file.
Prevent the error by checking for the existence of
the uci config sections before trying to use values from them.

Introduce option that enables the user to select max values
instead of averages for graphs if the user has disabled RRAsingle.
The option defaults to average values, which have been the default
in Luci statistics.
Remove 'optional' from RRASingle, as it is a key option for statistics.

With rrdsingle the average values are used for graphing. As the
timescale increases (say over a day or month) the average values
progressively reduce. Using the maximum value over the longer periods
is arguably no less deceptive but it does produce more informative
graphs.

Remove the usually empty standard deviation graph from the ping page.
The graph is empty for most users as collectd measures standard deviation
of individual pings inside the general interval of statistics collection.
Default setting for both ping interval and general collection interval
is 30s in Luci statistics, meaning just 1 ping per interval, which
leads to empty graph.
(To provide relveant data, the ping interval should be 1/4-1/5 of the
general collection interval. Even then the graph does not look very
informative due to different scaling than the latency graph.)
Note that this commit does not change collectd itself, which continues
to collect and calculate also the std.dev. data, which can be fetched
with 'rrdtool' if needed.

Clarify the CPU time consumption graph by removing the "idle" data from it.
Especially with light traffic, removing "idle" enables the graph

Implement support for alternative scaling of the y-axis.
By default, rrdtool will autoscale to 1,2,5,10,20,50,100,200,... etc.,
which is not always suitable (e.g. memory charts for device with 128 MB).
Rrdtool 1.0.50 already supports alternative autoscaling that creates
a tighter y-axis. Implement graph-level options in Luci statistics to
support those boolean options as "alt_autoscale" and "alt_autoscale_max".

CPU plugin in the Luci statistics was missing the label definitions,
so the field labels are like "cpu_system" instead of "System".
Add proper label definitions to CPU (like the other plugins already have).
The statistics graph was also missing softirq and interrupt stats, although colors
for them were defined. Softirq consumes massive amount of CPU especially with
any qos in use, so it is important for the user to see also that data. Add both
softirq and interrupt stats to the graph.

Earlier update to collectd 5.4.1 changed the field from "ping" to "value",

Collectd 5.5.0 introduced new data to conntrack plugin:
In addition to the number of tracked connections there is also
the static max conntrack value and the calculated use percentage.
Luci's conntrack plugin intrepretes "conntrack-max" as a new data instance
and includes it in the graph in addition to the real "conntrack" number.
Eliminate "max" from graph by specifying empty "" instance as data source.
