Introducing Munin 1.4.0! |
|---|
| 2 |
|
|---|
| 3 |
The most important features: |
|---|
| 4 |
* Better scalability through: |
|---|
| 5 |
- Multigraph plugins: One plugin, many graphs. |
|---|
| 6 |
This makes it possible to graph switches (and other things) efficiently |
|---|
| 7 |
In our test environment graphing one 16 port switch went from over 30 |
|---|
| 8 |
seconds to 3 seconds (please see snmp__if_multi and multigraph_tester |
|---|
| 9 |
plugins for examples). |
|---|
| 10 |
- Parallelized munin-graph (tunable number of processes) |
|---|
| 11 |
- Nesting of groups to any depth: |
|---|
| 12 |
"Conglomerate;US;New_York;Manhattan;6th-floor;" if you wish |
|---|
| 13 |
- Slightly better templates |
|---|
| 14 |
* Better security through TLS (SSL) session encryption and |
|---|
| 15 |
certificates to authenticate masters and slaves. |
|---|
| 16 |
* munindoc command to show plugin documentation. A majority of the |
|---|
| 17 |
plugins are documented now - no need to read the code - in most cases ;-) |
|---|
| 18 |
* New fab look on HTML pages, new graph colours with better contrast |
|---|
| 19 |
* Better SNMP support: SNMP version 1, 2c and 3, all modes of authentication |
|---|
| 20 |
are supported (but autoconfiguration of SNMP 3 is not quite there yet). |
|---|
| 21 |
(only applies to "most" SNMP plugins: those that have been ported to |
|---|
| 22 |
use Munin::Plugin::SNMP, some remain unported) |
|---|
| 23 |
* "includedir" in munin.conf includes all files in that directory in the |
|---|
| 24 |
configuration |
|---|
| 25 |
* More than 100 new plugins since the 1.2 series |
|---|
| 26 |
- Among them are a set of jmx based Java plugins to monitor JVMs. |
|---|
| 27 |
- A new and better MySQL plugin patterned on the Cacti MySQL plugin |
|---|
| 28 |
- PgSQL plugins based on generic Munin::Plugin::Pgsql module |
|---|
| 29 |
- Asterisk plugins |
|---|
| 30 |
- Netapp plugin |
|---|
| 31 |
- And much more |
|---|
| 32 |
* Slightly better "not Linux" support: |
|---|
| 33 |
- More Solaris plugins. Solaris plugin names have been aligned with |
|---|
| 34 |
the other platforms. |
|---|
| 35 |
- Core programs should play nice on all flavours of AIX |
|---|
| 36 |
- Nominal OS X ("darwin") support. (need someone to make a .img for us :-) |
|---|
| 37 |
- Some HP-UX plugins have been contributed |
|---|
| 38 |
- Good bunch of NetBSD plugins have been contributed |
|---|
| 39 |
- Still support for FreeBSD :-) |
|---|
| 40 |
- And many many other fixes |
|---|
| 41 |
* Ever better documentation everywhere, not least our web/wiki pages |
|---|
| 42 |
at http://munin-monitoring.org. |
|---|
| 43 |
* More bugfixes, both in the core code and plugins, than you can shake |
|---|
| 44 |
a stick at |
|---|
| 45 |
* Plugins can specify colours and printf format |
|---|
| 46 |
* Works well with RRD 1.3 |
|---|
| 47 |
* The project site has an exciting new url: http://munin-monitoring.org |
|---|
| 48 |
|
|---|
| 49 |
Other things you may want to know: |
|---|
| 50 |
* munin-update and munin-node (and family) have been refactored and are |
|---|
| 51 |
much nicer to hack now. |
|---|
| 52 |
* CGI graphing remains "in BETA" but we now have a FASTCGI script too. |
|---|
| 53 |

| 54 |
