Can anybody explain to enable rrd-archive step by step.

There are instructions in the text file accompanying the rrd-archive script. Basically, you need to edit the rrd-archive script to specify the loaction of your routers2.conf file (and possibly the location of Perl in the #! line, if you are on a UNIX system) and then use a scheduler to run the script every night at about 23:45.

I am using Windows system.I already added the location of those 2 files u mentioned.below is the snap shot of rrd-archive.pl.....

C:\mrtg\perl\bin
vim:ts=4


################# CONFIGURABLE LINES START ###############
# default location of routers.conf file
my( $conffile ) = "C:\mrtg\mrtg\bin\routers2.conf";
# default number of days after which to expire archived logs
my( $expiredaily ) = 31;
my( $expiremonthly ) = 12; # 1st of the month are Monthly


also want to know...instead of running rrd-archive.pl through task schedular...if i start it manually,will it create archive directory and archived the data.

will i have to change anything on rrd-archive.conf file or any other file?Pls. help,i require this feature enabled badly.

The rrd-archive.conf is simply an example of the lines to add to routers2.conf. The file is not required.

The first line should start with a #!

The vim line should start with a # or be removed.

Because you are using Windows, you might need to use a DOUBLE \ for a path separator in the $conffile definition (in everything other than Windows, a backstroke is the escape character)

You can run rrd-archive.pl manually if you want ant it should work. However, for the archives to be created correctly, it needs to be run every night just before midnight. You should run it manually the first time anyway to make sure there are no error messages.

Hi Steve,

upon double click on rrd-archive.pl is opening a command prompt...and showing some error msg.But i am not able to capture it properly bcos its closed so fast.I am attaching the msg with this post..first 2 line in rrd-archive.pl is as below...

#!C:\mrtg\perl\bin
vim:ts=4

also my( $conffile ) = "c:\mrtg\mrtg\bin\routers2.conf";


want to know..
1.rrd-archive.pl can be in any place or path or it has to be in some specific path.Currently i am manually try to run within below mentioned path...
C:\mrtg\routers2-v2.20\extras

2.When i run it manually will it automaticly created archive folder in where current .rrd files are there or i have to create it manually and then try?Currently i am seeing .rrd files are in C:\mrtg\wwwroot path.

3.R u saying that path should be..c:\\mrtg\\mrtg\\bin\\routers2.conf

Rather than clicking on the file in Explorer, open a command prompt and run it form the command line. Then you will be able to see the errors correctly.

The error message you attach indicates that you have made an error when configuring the script and put incorrect or too many backstrokes somewhere. You'll need to show me your modified script so I can spot the mistake.

1. You should be able to run it from any location.

2. It will automatically create the directory.

3. Yes. Because Windows uses backstrokes for path separator, you sometimes need to double them. This only affects windows (not unix, linux, macos etc), although Perl attempts to work around this problem.

Steve...thanks for ur support...

i am attaching the rrd-archive.pl for ur reference....also i am pasting u the error what i am getting when i run the script...

this is the error i got first when i run the script...

C:\mrtg\routers2-v2.20\extras>rrd-archive.pl
"use" not allowed in expression at C:\mrtg\routers2-v2.20\extras\rrd-archive.pl
line 41, at end of line
syntax error at C:\mrtg\routers2-v2.20\extras\rrd-archive.pl line 41, near "use
strict"
BEGIN not safe after errors--compilation aborted at C:\mrtg\routers2-v2.20\extra
s\rrd-archive.pl line 174.

Then i change the use strict; as #use strict;i got the below msg...

C:\mrtg\routers2-v2.20\extras>rrd-archive.pl
Can't modify constant item in scalar assignment at C:\mrtg\routers2-v2.20\extras
\rrd-archive.pl line 44, near "my"

Illegal declaration of subroutine main::readconf at C:\mrtg\routers2-v2.20\extra
s\rrd-archive.pl line 65.

i reverted back as use strict; and change the \ seperator as \\

c:\\mrtg\\mrtg\\bin\\routers2.conf...and got the below error...

C:\mrtg\routers2-v2.20\extras>rrd-archive.pl
Can't modify constant item in scalar assignment at C:\mrtg\routers2-v2.20\extras
\rrd-archive.pl line 44, near "my"

Illegal declaration of subroutine main::readconf at C:\mrtg\routers2-v2.20\extra
s\rrd-archive.pl line 65.

i kept it as usual for ur reference...attaching the same...

You have accidentally removed the '#' from the start of the second line. This is the comment mark and so the second line is now a syntax error. Put the '#' back at the start of the line and it should work.
