Folks, I've just set up a 4.7 unRAID and have gotten it working there now as well. I have a new version of the conf file at http://ruinedkingdoms.com/unRAID/mrtg-unmenu-package.conf Changes: I found a place in 4.7 emhttp to sneak in the mrtg page, it is different from 5.0, unfortunately :-( for 4.7, it's http://tower/log/mrtg/index.html for 5.0 beta 14, it's http://tower/mrtg/index.html (the same as before) make sure to include index.html in your url, emhttp is picky! added default support for /mnt/disk1 - /mnt/disk20 & /mnt/cache. the cache drive should be 1 drive 'number' higher than your last disk. If you want to double check, run this command from the command line after installing this new package: snmpwalk -v 1 -c public localhost dskPath this shows all the disks SNMP knows about (the blue depends on if you overrode the default values in the package configuration). I broke out the snmpd.conf file, so if anyone wants to make changes to the SNMP service, the file to change is /boot/config/snmpd.conf. make sure you do a /etc/rc.d/rc.snmpd restart after you make changes to snmpd.conf there is only one copy needed of the mrtg.cfg file now. turns out mrtg can't put a lockfile in a FAT32 partition (i.e. /boot), so I added a flag to have it put somewhere else. only thing this means is all you have to do is update /boot/config/mrtg.cfg with any changes. for advanced users, the flag I added was env LANG=C /usr/bin/mrtg --lock-file /tmp/mrtg_lockfile /boot/config/mrtg.cfg I think that's it, let me know if anyone notices any other problems. Hope you can all get MRTG working! Thanks, Adam Edit: I cant spel

It looks like emhttp is very, very picky. I have to actually include the index.html in the path, so for you it would be http://tower2/mrtg/index.html. Let me know if that works, in the latest version I put a comment in the description about the need to have the index.html in there.

Yup, that's basically what I did in the package install. I also set the WorkDir and the base options to whatever was in the User Configuration settings.

Actually, you don't want to do that... the /usr/local/sbin/emhttp is the binary for emhttp. I've got this fixed in my latest release, I'll post a longer explanation separately.

As far as I know, there is no Slackware mrtg package. My conf file installs one I compiled myself.

Yup, you've got the same issue as Lacehim, just a different path to the main web code in 4.7 I was piggybacking on emhttp only because it was there. As long as it works for you under lighttpd, that's all that matters :-) To answer your questions: 1. when you make changes to mrtg.cfg, make sure you update both files (fiddle with the one in /tmp/mrtg or wherever, but save it to the one in /boot/config when you're happy). I was hoping to just use the one in /boot/config all of the time, but mrtg has some weird problem (it thinks there are stale lock files in the /boot/config directory when there aren't). mrtg will see the changes the next time it runs via cron, although if you add a new chart, it will whine the first two times (missing log files, etc). I find that running it manually twice works better (instead of getting cron mails). env LANG=C mrtg /path/to/mrtg.cfg to update the mrtg landing page, run this indexmaker --output=/path/to/index.html /path/to/mrtg.cfg 2. Hmm, maybe I should break out the snmpd.conf file as well, that's where you need to make the changes to do other disks. As you've already made changes to the mrtg-unmenu-package.conf file, have another look in there and look for this bit: PACKAGE_INSTALLATION echo "disk /mnt/disk1" >> /etc/snmp/snmpd.conf PACKAGE_INSTALLATION echo "disk /mnt/disk2" >> /etc/snmp/snmpd.conf PACKAGE_INSTALLATION echo "disk /mnt/disk3" >> /etc/snmp/snmpd.conf PACKAGE_INSTALLATION echo "disk /mnt/disk4" >> /etc/snmp/snmpd.conf PACKAGE_INSTALLATION echo "disk /mnt/disk5" >> /etc/snmp/snmpd.conf PACKAGE_INSTALLATION echo "disk /mnt/disk6" >> /etc/snmp/snmpd.conf add a line that looks like PACKAGE_INSTALLATION echo "disk /mnt/cache" >> /etc/snmp/snmpd.conf and note the order that it's in relative to the other disk statements then just re-install the package. After that, change your mrtg.cfg to have the bit that looks for disk usage Target[server.disk]: dskPercent.1&dskPercent.2:public@localhost Title[server.disk]: Disk Partition Usage PageTop[server.disk]: <H1>Disk Partition Usage /mnt/disk1 and /mnt/disk2</H1> MaxBytes[server.disk]: 100 ShortLegend[server.disk]: % YLegend[server.disk]: Utilization LegendI[server.disk]: /mnt/disk1 LegendO[server.disk]: /mnt/disk2 Options[server.disk]: gauge,growright,nopercent Unscaled[server.disk]: ymwd Change the red number(s) to be the one which signifies the offset you put your /mnt/cache line in earlier (if it was the first disk line, that's 1... second would be 2, etc). Change the bolds to match for the legends and titles. If you only want the one disk, set both numbers to the same thing. Edit: also should mention, not sure how the cache drive works, but for regular disks in the array, mrtg throws an error when the array isn't running. Hope that helps, and let me know if you have any more questions.

Thanks! Ah, it looks like the emhttp directory is different in 4.7 (I only have 5.0 installed right now), I've got to find another USB stick to put 4.7 on so I can see what the differences on. Was hoping my "real" stick would have come in by now from newegg. I'll see if I can dig up one from somewhere and let you know what I find. It looks like other than the different web directory, it should work fine (neilt0 was able to get it working using lighttpd).

I fiddled with it some more and used prostuff1's suggestion, now it works and stays working upon reboot. Cleaned up some and added comments to the conf file and posted my sample mrtg.cfg (that does all the extra things), but for now the base package install just sets up ethernet interface monitoring. So, for my use, it is fine. I'll see if anyone else is interested before I put more effort into this package. I've got another one I'm looking into trying to get working. Just to have all this info in the same place, here is the link to the conf file (always points to the newest version) http://ruinedkingdoms.com/unRAID/mrtg-unmenu-package.conf the link to the sample screenshot (with all sorts of charts) http://ruinedkingdoms.com/unRAID/mrtg_sample_index.png the link to the mrtg.cfg file that shows how to do everything in the sample screenshot (the package just sets up the ethernet interface(s) by default) http://ruinedkingdoms.com/unRAID/mrtg.cfg Thanks for everyone's help.

Thanks guys, will have a look. My system's doing a parity check so probably won't be for a while. :-) I got together a good sample page of a standardized set of charts, which I think I'll set up options for including in the future. Each of the charts is a link that goes to more historical data (and hard numbers). I outsmarted myself with the index.html generation though, turns out mrtg comes with a script that generates a landing page based upon your mrtg.cfg file :-) Here is what it looks like: http://ruinedkingdoms.com/unRAID/mrtg_sample_index.png

Thanks for the feedback! I changed the cron line to your suggestion (I hadn't considered that). I also removed the PHP dependency as I was only using it for the index.php. I'm now just using a one-line perl script to generate an index.html file (so the mrtg page is now http://tower/mrtg/index.html). I also ended up running mrtg twice as part of the install so no cron warnings are sent out. I haven't tested it on 4.7 yet as I have only one USB memory stick (which is blacklisted) and I'm waiting for a better one to show up :-) One thing I'm concerned about is I checked the version of Slackware for 5.0 and it was 13.1, so that is the version of tgz files I used in my conf file and where I compiled the mrtg tgz. I'm guessing 4.7 is using Slackware 12.x, would that cause a problem? Also, although it installs just fine manually, it doesn't seem to want to auto install. If I run /boot/packages/mrtg-2.17.3-i486-0.tgz.auto_install after a boot, it works fine. I suspect it's getting auto installed before perl, but I can't see the messages on the console because it scrolls by too fast (and I can't find a message log file). Is there any way to have the mrtg package auto install get scheduled for after the perl package install (besides adding a line to the 'go' script)? Sorry to bug you with these questions. Thanks, Adam

Folks, I just discovered unRAID recently and am setting up a box. I was fiddling around with unRAID packages while waiting for my files to copy and noticed that there didn't seem to be any traffic plots. So as a learning experience I got MRTG and SNMP working on my unRAID 5 beta 14. Everything seems to work, but it's all very much a work in progress. (it's a beta package on a beta unRAID release!) If you haven't heard of MRTG, it's a traffic grapher (http://oss.oetiker.ch/mrtg/). They way I've gotten it working is it: 1. requires unMenu 2. requires perl (via the unMenu package), doesn't require gcc (I made a binary package) 3. defaults to setting up a ro snmp community public (can be overridden) 4. creates a base mrtg.cfg file in /boot/config if there isn't one there (so you can customize it and not have it disappear) 5. creates a /tmp/mrtg directory where the log/png files are stored (these will disappear upon reboot). The directory is user definable so, in theory, you could stick it on a cache drive or even on the array and have a full history saved. MRTG's log files don't grow past a certain size, so no worries about running out of ram. 6. adds a 5 minute recurring cron job to update the mrtg charts 7. piggybacks on emhttp (the unRAID GUI) to create a simply/crappy website at http://tower/mrtg/index.html'>http://tower/mrtg/index.html (for unRAID 5.0b14) or http://tower/log/mrtg/index.html (for unRAID 4.7) which shows all the interfaces' daily charts and allows for drilling into the week/month/year data (make sure you include the index.html!) Things to keep in mind: - MRTG will give warnings the first 2 intervals as it has to create log files/image files (so if you have root email forwarded, you will see it) no longer an issue - not sure how to get the index.php index.html to show up as the default page under http://tower/mrtg using emhttp - probably some bugs in the unMenu conf file (it's my first one, so bear with me) - all the dependencies other than perl take up 7.7MB of tgz files (and all but mrtg are Slackware packages) the conf file is here http://ruinedkingdoms.com/unRAID/mrtg-unmenu-package.conf I (hopefully) attached a sample chart (a daily one) There's no reason why you couldn't set up a bunch of other machines' interfaces (routers, other machines, etc) manually in the mrtg.cfg file and have them all tracked. Also, SNMP allows for disk space/load average tracking as well as eth interface tracking so you could theoretically do disk space/load average charts with MRTG as well. Anyway, if anyone ends up using it, let me know if you notice any issues and if you have any suggestions for the conf file. Cheers, Adam Update 2012-01-09: I've setup a 4.7 unRAID USB and this now works there as well. The URL is unfortunately different between 4.7 and 5.0b14 for 4.7, it's http://tower/log/mrtg/index.html for 5.0 beta 14, it's http://tower/mrtg/index.html'>http://tower/mrtg/index.html (the same as before) make sure to include the "index.html" in your url. You wouldn't think it was required, but it seems emhttp requires it Also, here is a sample screen shot of a bunch of different charts http://ruinedkingdoms.com/unRAID/mrtg_sample_index.png and the mrtg.cfg file that creates it http://ruinedkingdoms.com/unRAID/mrtg.cfg
