The current statistics options make the file sizes as follows: <ul> <li>health rrd 2.5megabytes</li> <li>reachability rrd 756kilobytes</li> <li>interface rrd 568kilobytes.</li> </ul> <p>All of these RRD's make up the database and for a few routers could become quite large quite quick. </td> </tr> <tr> <td width="100%" colspan="3"> <a name="interfacefile">Q. What is the format for the "interfaces" file?</a> <p>A. The interfaces file is automatically generated by the NMIS system. You don't need to manually make these interface files. There is also an interfaces.dat which is all the interface data for all the devices put together also generated automatically by the update process.</td> </tr> <tr> <td width="100%" colspan="3"><a name="loadoids_file">Q. There are problems with the loadoids_file subroutine?</a> <p>A. This is a modification to the SNMP Simple package, SINS has made up a distribution of SNMP_Simple availble here <a href="http://www.sins.com.au/public/SNMP_Simple_NMIS.tar.gz">SNMP_Simple_NMIS.tar.gz</a></td> </tr> <tr> <td width="100%" colspan="3"><a name="load_mibs">Q. How do I add mibs to NMIS?</a> <p>A. You need to edit the loadmibs.pl script, put the names of the mibs into the script and generate the OID files. Not straight forward if you don't program in Perl but quite easy really. Something like: <pre>mibdump.pl mibdir=/usr/local/share/snmp/mibs mibs=router outfile=/data/nmis/mibs/cisco-router.oid</pre> You will need copies of MIBS, some available at <a href="http://www.sins.com.au/public/">http://www.sins.com.au/public/</a> </td> </tr> <tr> <td width="100%" colspan="3"><a name="ping">Q. I am having problems with Ping?</a> <p>A. NMIS now uses Perl Net::Ping and requires NMIS to be run with Root privileges. For backwards compatibility the old routines are included which execute Unix Ping. </td> </tr> </table> </BODY> </HTML>
