Rrd files not updating

This is a bug in recent versions of the Perl module Net:: Server, see A guide to server configuration is in the wiki page

Some interesting things that are not covered in that page is shown in this FAQ.

For a more thorough definition of RPN, take a look at the man-page for is the same as the graph_order-arguments above.

rrd files not updating-28

The server will query the node and show all the services(plugins) it offers. Everything you define in overrides the plugin's value.

Example: On the host foo.example.com, I want to set the This also applies to almost all other parameters in the plugins, even if overriding those might not make much sense.

The syntax in the entry is [plugin_name].[fieldname].(warning|critical) [value].

On the Munin page for the individual plugin, the fieldnames are listed as "Internal name" below the graphs.

If you want to specify a cdef for the 'whole stack', you can use the fieldname defining the special stack. [some.machine.boo] total_mail.graph_order total_received total_mail.graph_title Mail received by machine1 and machine2 total_mail.graph_vlabel mails/min total_mail.total_received.label not_used total_mail.total_received.stack \ machine1=machine1dom:exim_mailstats.received \ machine2=machine2dom:exim_mailstats.received total_mail.total_total_received,60,* [some.machine.boo] total_mail.graph_order total_received total_mail.graph_title Mail received by machine1 and machine2 total_mail.graph_vlabel mails/min total_mail.total_received.label mails per minute # Now used total_mail.total_\ machine1dom:exim_mailstats:received \ machine2dom:exim_mailstats:received total_mail.total_total_received,60,* [foo.example.com] total_mail.graph_order total_received total_mail.graph_title Mail received total_mail.graph_vlabel mails/min total_mail.total_received.label mails per minute total_mail.total_\ exim_mailstats.received \ # Collects from itself (foo) bar.example.com:exim_mailstats.received \ # Collects from bar Customer;com:exim_mailstats.received # Collects from a different domain ('Customer') and host ('com') total_mail.total_\ exim_mailstats.received \ # Collects from itself (foo) bar.example.com:exim_mailstats.received \ # Collects from bar Customer;com:exim_mailstats.received # Collects from a different domain ('Customer') and host ('com') total_mail.total_\ example.com;foo.example.com:exim_mailstats.received \ # Collects from itself example.com;bar.example.com:exim_mailstats.received \ # Collects from bar Customer;com:exim_mailstats.received # Collects from a different domain ('Customer') and host ('com') This will establish a tunnel between TCP ports 5050 on the calling machine to 4949 on the called machine.

It will also send ssh in the background after possibly asking for a passphrase, a password or something like that.

Since we are using a key made for this purpose, we have to specify that file with this key.

, better enhance the plugin for it to support plugin configuration and submit it upstream.

This will save you lots of work on future maintenance when you will upgrade the plugins packages. When you create a cdef-field, be sure to use the fieldname at least once in the definition, or rrdgraph will croak with an error.
