Version 2.22 of Routers2, the frontend for MRTG/RRD, is now available for
download from http://www.steveshipway.org/software/


Many thanks to everyone who contributed to testing and development.  This
version has been in general use at our site for many months without
incident; also, it properly supports the new RRD caching daemon functions in
RRD 1.4 and the RRD trunk version.


As always, please let me know of any issues you have with this.  With the
wide variety of different configurations out on the net it is never possible
to test everything - any reported problems will be addressed as soon as


An update for the MRTG/RRD/Routers2 book to cover these changes and the new
MRTG version is in the pipeline.






v2.22 20/5/11

! Popup actuals gave wrong suffix for value <1

! tzset was not being called after restoring saved timezones.  Oops.

+ Add support for rrdcached via env var, cfg file directive, or

+ Add auto flush of rrdcached cache if necessary

+ Add tests for RRD version and rrdcached settings in verify page

+ Automatic detection of speedycgi, fastcgi, mod_perl

+ Add thumbnail mode graphs with gstyle=A or gstyle=B.  This requires RRD1.4

  as it uses the no-axis option.

+ Full support for experimental RRD 1.4.999 rrdcached/TCP allowing RRD files

  to exist on remote server.  Note that this kills off RRD Archiving though

  there is no way to remotely detect the archives.

^Beta1 10/8/10

+ Proper wildcard support for Include: (to match MRTG 2.17)

! (Lyle Giese) square brackets could not be in routers2.conf data

! trend.cgi would not work with RRD caching daemon.  Still doesn't work
properly, but

  now disables the env var if set

! trend.cgi did not support libadd directive correctly.

! Type 6s was missing.

+ Allow 'routers.cgi*HRule[]: value "desc" #xxxxxx' to specify a colour
