TO-DOs:

• Work with Mark Moore to synchronize CGD use of Nagios and SCD's. Monitor his hosts the same way he does.
• Security: install Apache2, then look to see if there are any old emails from Rich Johnson that mention Nagios security.
• Check-bgp-new, there are 2 emails from people asking about it.
• Check-icmp, there are emails from people ready to help make it work.
• System Administration
  • High availability: just put nagman2 at FL, rsync nagman to nagman2 regularly, and allow nagman2 to ping the network along with nagman. Routers and hosts send SNMP traps to a single address - make them send to bothh machines. Remote member machines accept pings and SNMP packets from just one address - make them do so from both machines. The paradigm is: nagman2 is the same as nagman, you will get the same basic functionality from either, you can connect to either.
  • nagman is running Debian. Remaining tasks are 1. Ask David to help set up RAID 2. clean up the "Add/Remove Server" work request for nagman and fl-nagman and close it.
• How to monitor etherchannels? On 2006-07-06, when Scot brought down 1-2 of the etherchannel between the FRGP and Abilene, the NOC didn't notice.
• How can I make Nagios understand when there's a power failure at Foothills? The UPS's will trap. Can Nagios correlate? If 2 or more UPS's at foothills trap within a certain time window, consider Foothills to have a power failure. Is there a way? Ask the Nagios mailing list?
• OpenView sends Ed Snyder email whenever a UPS traps. It should be easy to get Nagios to do it.
• Make Nagios poll for SNMP values and send email when the VPN server(s) are under 5 or over 100. Use check_snmp or snmp4nagios. OpenView does this now, so we need Nagios to do it before we can dump OpenView. Use this capability to monitor Movaz laser power levels.
• Openview provided the SNMP MIB browser application. Nagios doesn't have one, but Net-SNMP has "tkmib". Jeff has used it. Load MIBs and try it.
• Figure out how best to handle SNMP traps.
• It sends 2 emails for every event: one to siemsen and one to nagios-admin.
• Why does it take Nagios over 2 minutes to detect that oryx is down, when oryx is a tier1 host?
• Phone messaging works, but what is the "ne|", the subject? IS there a way to improve the received messages?
• Is there a way to use UCAS passwords on Nagios accounts?
• Investigate graphic submaps. The current single graphic map is so cluttered it's useless. Lynda says she's seen Nagios do submaps. This will make the "Locate host on map" icons on Nagios web pages more useful - right now they take you to the single map.
• Can I separate "security" hosts so that the rest of us don't see the status of their stuff?
• use Postgresql on netserver as source of Nagios "ncar" config file. See David's Postgres notes.

  	basics:
  	psql nnd
  
  	To see all switches:
  	select ip,short
  	from system,groups_system,groups
  	where system.id=groups_system.system_id and
  	groups.id=groups_system.group_id and
  	short='All_Switches';
  	
  	To see all tables defined in the database:
  	select * from pg_class;
  	
  	See Dave's schema.txt file.  You can check it out from CVS (Dave's
  	CVS notes are at http://www.scd.ucar.edu/nets/tools/cvs/)
  	cd /tmp
  	cvs co nnd
  	cd nnd
  	more schema.txt
  
  	to be postgres, must su as root then "su postgres"
  	psql tricks:
  	\d
  	\z
  	\dt

• To write a Perl program that parses Nagios configs, I installed the Nagios::Object module onto nagman. The distro contains a sample program named parse.pl that parses a Nagios config file. I ran it with

  parse.pl -d -v 2 -n /usr/local/nagios/etc/ncar.cfg

  to generate Nagios configs, I need this from the Postgresql database:
  • host name
  • host IP address
  • tier
  • is it monitored (implies a web file exists)
  • group (NETS, JOSS, etc.)
• Nagios doesn't do discovery. We will keep up-to-date with adds/removes/changes by relying on the add/remove work requests.
• Text messaging/paging
  It works. Now to make it useful by limiting the number of text messages that are received and the value of the text.
• Make web pages for security hosts.
