- mrtg-nw-guide - MRTG for NetWare
- SSYYNNOOPPSSIISS
- This guide is intended to aid in the installation and con-
- figuration of MRTG on a NetWare server.
- OOVVEERRVVIIEEWW
- MRTG is a relative newcomer to the NetWare platform. Ear-
- lier versions of NetWare could not run MRTG natively for
- several reasons:
- +o Absence of NetWare OS support in the MRTG package.
- +o A NetWare server commandline length limitation.
- +o Absence of the Rateup executable (Rateup.nlm).
- +o A standard installation method.
- +o Problems with NetWare's implementation of Perl.
- Support for the NetWare OS has now been fully added into
- MRTG, beginning with MRTG release 2.12.2.
- Liberallly minded operating systems support a commandline
- length approaching 1000 characters. In such environments
- it was an easy matter to pass the sometimes high number of
- parameters used by MRTG's Rateup executable directly on
- the commandline. Until NetWare 6.5, NetWare had a command-
- line limit of 512 characters. This limitation was also
- removed for NetWare 6.0 by Service Pack 5. For other Net-
- Ware versions and earlier Service Packs, this limitation
- remains. To permit a 'standard' interface for NetWare, the
- Rateup executable has been modified to also read its
- parameters from a file, and the MRTG script has been modi-
- fied to support this method on a NetWare platform. (See
- New Rateup Switch)
- A Rateup NLM is now available, along with the necessary
- scripts to build it if required. See the NetWare Support
- section of this document for further details. Addition-
- ally, mrtg.pl has been revised because of the unique (to
- NetWare) name of executables (NLM).
- The absence of a specific installation procedure has
- caused MRTG to fail in the past because the Perl script
- could not find or load the Rateup executable. The instal-
- lation method supplied here will solve this problem for
- now.
- The MRTG.pl script in the 2.12.2 (or later) version of
- MRTG has been configured to suit all likely versions of
- NetWare able to use Perl5, and bypasses all of the known
- problems with NetWare Perl running MRTG.
- PPRREERREEQQUUIISSIITTEESS
- You will need the following:
- +o Perl 5.8.0 for NetWare with latest Perl Updates
- (February, 2005 or later; previous versions MAY work)
- +o NetWare 5.1 w/ SP8, NetWare 6.0 w/ SP5 or NetWare 6.5
- w/ SP2.
- +o A copy of the MRTG Package (v2.12.2 at time of writ-
- ting)
- +o Three .ncf files to execute the Perl scripts at the
- NetWare server console.
- +o A copy of the Rateup NLM (Pre-built or compiled)
- +o Optionally, any NetWare supported Web Server
- (Netscape, Apache 1.3 or 2.0)
- For copies of the .ncf files and Rateup NLM, see NetWare
- Support in this document.
- IINNSSTTAALLLLIINNGG MMRRTTGG
- 1. Install the latest Perl 5.8.x release on your server.
- See the Perl documentation for details.
- 2. Create the following directories:
- SYS:/Mrtg
- SYS:/Mrtg/bin
- SYS:/Mrtg/contrib (Optional for this document)
- SYS:/Mrtg/doc (Optional for this document)
- SYS:/Mrtg/html
- SYS:/Mrtg/html/images
- SYS:/Mrtg/html/work
- SYS:/Mrtg/lib
- SYS:/Mrtg/logs
- SYS:/Mrtg/translate
- 3. Copy from the MRTG package the following files:
- bin* to SYS:/Mrtg/bin All files. See Note 1.
- Note 1: Add a .pl extension to the mrtg, cfgmaker and indexmaker files.
- The rateup.exe will NOT be needed on the NetWare server.
- contrib* to SYS:/Mrtg/contrib/ Include sub-directories
- doc* to SYS:/Mrtg/doc/ All files
- images* to SYS:/Mrtg/html/images/ All files
- translate* to SYS:/Mrtg/translate/ All files. See Note 2.
- Note 2: For English-only language support, all translate files EXCEPT Locales_mrtg may be deleted.
- lib* to SYS:/Mrtg/lib Include sub-directories. See Note 3.
- Note 3: This will create the SYS:/Mrtg/lib/mrtg2 and ./pod directories.
- 4. Create copies of the three .ncf files and install
- them:
- *.ncf to SYS:/Mrtg/bin
- See NetWare Support in this document for details on
- how to create copies of these files.
- 5. See Compiling Rateup.nlm"> in this document for
- details on compiling the Rateup NLM yourself if
- desired. A prebuit verion is available in the
- .mrtgbin directory where it must remain.
- CCOONNFFIIGGUURRIINNGG MMRRTTGG
- +o Refer to Novell documentation on configuring and load-
- ing SNMP support on your server if this is the device
- to be monitored.
- +o Edit sys:/mrtg/bin/MakeMrtgCfg.ncf:
- - replace ccccc with the GET community name for the SNMP device (typically 'public'),
- - replace ddddd with the DNS name or IP address of the device to be monitored.
- e.g public@www.myserver.com, public@10.202.65.180
- Note 1: These are NOT mail addresses, they just look like one!
- Note 2: If multiple devices are to be monitored, add their entries to the same line:
- e.g perl cfgmaker.pl public@www.myserver.com public@10.202.65.180 > sys:/mrtg/bin/mrtg.cfg
- In this "Getting Started", it is 'suggested' to only
- monitor a single device.
- +o At the server console, run:
- sys:/mrtg/bin/MakeMrtgCfg.ncf
- This will create Mrtg.cfg in sys:/mrtg/bin.
- +o Edit the Mrtg.cfg configuration file created in the
- previous step. Note the following:
- It was found, when testing MRTG on a NetWare 6.5
- server using a NIC Interface, that mrtg.cfg contained
- the following message:
- ### Interface 1 >> Descr: 'Intel(R)-8255x-based-Network-Connection'...
- ### The following interface is commented out because:
- ### * has a speed of 0 which makes no sense
- #
- ...
- If this occurs, edit MakeMrtgCfg.ncf and add the fol-
- lowing parameter as shown:
- perl sys:mrtgbincfgmaker.pl --zero-speed=nnn public@10.202.65.180 > sys:mrtgbinMrtg.cfg
- where nnnnnn is the interface speed in bits per second.
- For a 100 Megabit LAN NIC, nnn = 10000000. It will be
- necessary to re-execute the MakeMrtgCfg.ncf script
- before continuing with this section.
- Below line 16 (*** Global Defaults), add:
- HtmlDir: <a path> e.g HtmlDir: sys:/mrtg/html
- ImageDir: <a path> e.g ImageDir: sys:/mrtg/html/work
- LogDir: <a path> e.g LogDir: sys:/mrtg/logs
- IconDir: <a path> e.g IconDir: ./images
- Note 1
- The HtmlDir entry specifies where MRTG will create
- its HTML pages.
- Note 2
- The ImageDir entry specifies where the created
- graphic icons are placed.
- Note 3
- The IconDir entry specifies where the supplied
- MRTG icons are located. It MUST be a relative
- path from HtmlDir or absolute URL. The value shown
- is recommended.
- +o At the server console run:
- sys:/mrtg/bin/RunMrtg.ncf
- several times. By the third time it should run without
- showing error messages on the console screen. This
- should create:
- +o A HTML page in the (HtmlDir) directory for each
- monitored device,
- +o A .dat file in the (ImageDir) directory for each
- monitored device,
- +o Several .png icons in the (ImageDir) directory,
- +o Some log file entries in the (LogDir) directory.
- Note: If you experience a "Use of uninitialised value
- in split" error, it will be necessary to create a
- 'Path' environment variable at the server console; use
- the following example
- env path="SYS:" (The actual value is immaterial, as long as the var itself exists.)
- +o Edit sys:/mrtg/bin/MakeMrtgIndex.ncf. Change the indi-
- cated <path> shown in the following example to match
- the value entered for (HtmlDir).
- perl --noscreen sys:/mrtg/bin/indexmaker.pl sys:/mrtg/bin/Mrtg.cfg > <path>/index.html
- +o Create an index.html page linking the seperate device
- HTML page(s). At the server console, run:
- sys:/mrtg/bin/MakeMrtgIndex.ncf
- This will create index.html in the (HtmlDir) direc-
- tory.
- +o Optionally, configure a Web Server to permit access to
- the directory specified in (HtmlDir) to view the MRTG
- graphs remotely, at, for example:
- http://ip_or_dns/mrtg/index.html
- A sample configuration for an Apache Webserver is
- shown:
- Alias /mrtg/ "SYS:/mrtg/html/"
- <Directory "SYS:/mrtg/html">
- AllowOverride None
- Order allow,deny
- Allow from all
- </Directory>
- +o Set the property of the directory pointed to by
- (ImageDir), to 'Purge Immediate'.
- +o Finally, read the MRTG documentation for much more
- detailed configuration/usage information.
- Welcome to MRTG!!
- MMAAKKEE MMRRTTGG RRUUNN AALLLL TTHHEE TTIIMMEE
- MRTG can be made to run periodically by at least two
- means:
- +o Using CRON Scheduling
- +o Running MRTG in Daemon Mode
- CCRROONN SScchheedduulliinngg
- To use CRON scheduling, create a CRON Scheduler entry to
- execute the RunMrtg.ncf file on a frequency appropriate
- for the server environment and information desired. The
- following entry in the sys:etccrontab file will execute
- MRTG every five minutes:
- 0,5,10,15,20,25,30,35,40,45,50,55 * * * * sys:mrtgbinrunmrtg.ncf
- The CRON Scheduler (cron.nlm) can be started automatically
- by adding it in AUTOEXEC.ncf or, manually loading it at
- the server console.
- MMRRTTGG iinn DDaaeemmoonn MMooddee
- Refer to the MRTG-Reference document for information about
- the 'RunAsDaemon' option. Its use is outside the scope of
- this document.
- TTRROOUUBBLLEESSHHOOOOTTIINNGG
- Read the MRTG documents, Perl documents or, finally, sub-
- mit questions to the MRTG User forums.
- For NetWare specific issues, submit questions to the Perl
- forum at news://developer-forums.novell.com/novell.dev-
- sup.perl (Novell Developer Forums).
- CCOOMMPPIILLIINNGG RRAATTEEUUPP..NNLLMM
- In addition to the rateup.c and Makefile.Netware supplied
- with the MRTG release, you will also need:
- +o Metrowerks CodeWarrior with NetWare Support OR GCC
- Compiler (v3.0.3 or later) with NlmConv Utility
- +o Novell LibC NDK (February 2004 or later)
- +o GD Graphics Library (v2.0.33 or later)
- +o LibPNG Graphics Library (v1.2.8 or later)
- +o ZLib Library (v1.2.3 or later)
- +o The get_ver.awk script
- +o A copy of the GNU build tools. (See http://source-
- forge.net/projects/gnuwin32/)
- The auxiliary libraries can be obtained from:
- GD Graphics Library. (See http://www.boutell.com/gd/ )
- PNG Graphics Library. (See http://libpng.source-
- forge.net/ )
- zLib Compression Library. (See http://www.gzip.org/zlib/
- )
- Edit the Makefile.Netware file as required to match your
- installation paths; search the file for the key word
- 'Edit'.
- NNEETTWWAARREE SSUUPPPPOORRTT
- For copies of the NCF and get_ver.awk scripts, see
- Appendix.
- For NetWare specific issues, submit questions to the Perl
- forum at news://developer-forums.novell.com/novell.dev-
- sup.perl (Novell Developer Forums).
- To move the MRTG application to a volume other than SYS:
- you will need to edit the NCF scripts provided plus the
- MRTG[.pl] script itself in two places.
- NNEEWW RRAATTEEUUPP SSWWIITTCCHH
- The MRTG[.pl] script, when used on a NetWare platform,
- uses Rateup[.nlm] with the new commandline switch:
- RATEUP -f filename
- where the filename parameter can include a leading path
- element.
- The file format is exactly the same as that used on the
- commandline by other operating systems, including the
- leading path and name of the Rateup NLM.
- AAPPPPEENNDDIIXX
- The Appendix includes 'copies' of the following files:
- +o The NCF files used during MRTG configuration,
- To create copies of these files, simply 'cut and paste'
- into your favourite 'tteexxtt eeddiittoorr' and save under their
- respective names. You should remove the leading space from
- each line.
