NMIS 8.3.24G is being released for general availability, This release provides many bug fixes and a few new features.
Install CPAN Modules
NMIS8 now requires Net::Syslog, see the 8.3.9G patch for info on SMTP::SSL
cpan install Net::SMTP::SSL # (required for 8.3.9G) install Net::Syslog
Patch NMIS8 code with the NMIS8.3.18G update
#Backup current NMIS code and config including models DATE=`date "+%Y-%m-%d-%H%M"` cd /usr/local/nmis8 tar cvf ~/nmis8-backup-$DATE.tar ./admin ./bin ./cgi-bin ./conf ./install ./lib ./menu ./mibs ./models #Make sure NMIS is working before you patch it. /usr/local/nmis8/bin/nmis.pl type=collect debug=true node=<node to test> #Get CP working right.

Checking Model Changes
NMIS 8.3.24g includes many device modelling enhancements, improved graphs and more, if you have made no changes to your models you can overwrite your existing models, otherwise you will need to merge the new models with the existing models, that requires consideration outside this document. To overwrite your existing models:
cp /usr/local/nmis8/models-install /usr/local/nmis8/models
Patch NMIS8 Config
Your NMIS installation may have settings that you have changed from the default installation. If you would like to keep these changes you will need to merge the additional fields that have been added into the stock configuration into your custom configuration. NMIS provides a tool called updateconfig.pl to help you do this:
# merge changes for new NMIS Config options. /usr/local/nmis8/admin/updateconfig.pl /usr/local/nmis8/install/Config.nmis /usr/local/nmis8/conf/Config.nmis /usr/local/nmis8/admin/updateconfig.pl /usr/local/nmis8/install/Access.nmis /usr/local/nmis8/conf/Access.nmis
Most of the config files will likely be the same as the install version, for these you can just copy the new versions
# copy newer configuration files (check that you don't have local changes to these files before running) cp /usr/local/nmis8/install/Tables.nmis /usr/local/nmis8/conf cp /usr/local/nmis8/install/Table-*.nmis /usr/local/nmis8/conf cp /usr/local/nmis8/install/Logs.nmis /usr/local/nmis8/conf cp /usr/local/nmis8/install/Users.nmis /usr/local/nmis8/conf cp /usr/local/nmis8/install/Services.nmis /usr/local/nmis8/conf cp /usr/local/nmis8/install/License.nmis /usr/local/nmis8/conf cp /usr/local/nmis8/install/Modules.nmis /usr/local/nmis8/conf cp /usr/local/nmis8/install/Escalations.nmis /usr/local/nmis8/conf cp /usr/local/nmis8/install/Portal.nmis /usr/local/nmis8/conf cp /usr/local/nmis8/install/logrotate.conf /usr/local/nmis8/conf cp /usr/local/nmis8/install/users.dat /usr/local/nmis8/conf

NMIS Configuration
You will need to verify the following configuration options have been set correctly or removed.
nmis_summary_poll_cycle
There are some updates to improve UI and polling synchronisation. Check the following configuration option for nmis_summary_poll_cycle, it should be set to false and the summary update added to the crontab.
'nmis_summary_poll_cycle' => 'false',
global_nocollect_noDescription
This needs to be set to blank unless you intentionally want it to be "true"
'global_nocollect_noDescription' => '',
fastping_node_poll
We have found this is better set to a lower number, but if your experience has been otherwise, you do not need to change it.
'fastping_node_poll' => '200',
tables_case_sensitive_keys
This config setting "tables_case_sensitive_keys" is redundant, it is being done in the Tables.nmis file now.
File Permissions
Change Config.nmis to tell NMIS to use the new file permission scheme
%hash = (
--SNIP--
'system' => {
--SNIP--
'os_execperm' => '0770',
'os_fileperm' => '0660',
Authentication
We recommend updating the authentication system from apache to htpasswd (so NMIS does authentication instead of Apache). 3 steps need to be taken to change this.
Change Config.nmis to tell NMIS to use htpasswd
%hash = ( --SNIP-- 'authentication' => { --SNIP-- 'auth_method_1' => 'htpasswd', # <= change this FROM apache TO htpasswdBackup old apache configGenerate new apache configuration (if you have customised yours edit it and remove the auth portions instead of generating a new one)
#backup old config cd /etc/httpd/conf.d/ cp 00nmis.conf 00nmis.conf.pre-8.3.24G.bak
Create new config to replace old config and restart apache
/usr/local/nmis8/bin/nmis.pl type=apache > /etc/httpd/conf.d/00nmis.conf service httpd restart
Fix Data Type for Some Counters
Fix Data Type on mib2ip Counters
Run this command to make all the DS's COUNTER instead of GAUGE
/usr/local/nmis8/admin/rrd_tune_mib2ip.pl run=true change=true
Fix Data Type on TopChanges Counters
Run this command to make TopChanges the DS's COUNTER instead of GAUGE
/usr/local/nmis8/admin/rrd_tune_topo.pl run=true change=true
Restart Daemons
/usr/local/nmis8/bin/fpingd.pl restart=true
Update the Font Cache
In order to make RRD run faster it really helps to update the font cache
fc-cache -f -v
