Hello. Recently, we've built a new DHCP server, with our usual MRTG instrumentation, on top of RedHat Enterprise Linux ES 4.7 (Nahant Update 7), and have found that MRTG (2.16.0 with traditional rateup) is generating GIF instead of PNG files. This is a problem for us, as all our other MRTG boxes use PNG, and this is what the portal system which sits in front of them all expects. As a result, we have broken links due to URLs ending in ".png" corresponding to filenames ending in ".gif".
We don't have this problem with ES 4.3. It appears that, since some subsequent upgrade to ES 4, the PNG support which the MRTG build script expects to find is no longer included in the way it used to be, and is either absent or unrecognized. While we're working on resolving this, I wonder whether anyone else has found the solution already? I suspect that some RPM related to 'gd' needs to be added -- perhaps 'gd-devel', as the base RPM for 'gd' is already installed. No doubt we can bypass the problem by using RRDtool and an acceptable front-end. This isn't an applicable solution for us at present, so please "save your breath to cool your porridge" if this is what you would recommend. I do want to do move over to the "one true way", but only when I have worked out how not to lose some favourite features of the _traditional_ MRTG display. 8-) Thanks in advance for sharing any relevant experience. If no-one can help, one of us will report our results in due course. Happy Christmas and New Year!
