Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP ABSTRACT: It's important as an IBM Domino administrator to get metrics on your servers so that you know what's going on in your "Brewhouse". There are also many ways to obtain this very valuable information, like 3rd party tools and even the IBM Domino Administrator client. What many don't know is that there is also another way to capture this very valuable information. SNMP (Simple Network Management Protocol) is an Internet-standard protocol for managing devices on IP networks. In this session, you will learn more about it, what it can give you, how to set it up, and ways to 'drink in' or monitor the information. With proper configuration, administrators not familiar with IBM Domino can obtain and use key IBM Domino server metrics. Homebrew your own metrics by attending this session!
  • 6. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP Existing Domino Monitoring Options • Traditional Monitoring – Monitoring Configuration database (EVENTS4.NSF) – Statistics Reports database (STATREP.NSF) • Domino Domain Monitoring (DDM) • Domino Administrator client • 3rd Party Tools
  • 7. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP The Backstory
  • 8. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP What is SNMP? It’s not Simple (until you understand it) It’s not just for Networks It’s for Management It’s a Protocol It’s an industry standard communication protocol for talking to devices that are connected to networks. If a device says it’s manageable it likely has SNMP capabilities.
  • 9. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP How can SNMP help you? SNMP can be used to measure something immediately or over time so that you can make better decisions. SNMP traps can be sent to alert you of an event (i.e. drive failure). SNMP can be used to measure and then set thresholds that trigger alerts.
  • 10. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP How can SNMP help you? cont SNMP is an enabler that allows visibility into real information so you’re not guessing. SNMP can answer questions like: – Do we need more phone lines? – Do we need more Internet bandwidth? – Why is my storage running slow? • Is it CPU? Memory? Disk I/O? Network?????? – Am I going to run out of disk space 3 months from now? – What was going on 20 minutes ago when everyone said the network was running slow? – Do I have a POS system that is getting hard drive errors and will probably die 3 weeks from now? – What temperature was it in the data center at 4 am 3 weeks ago? – How many mail messages are in the queue?
  • 11. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP Why use SNMP instead of a special tool? SNMP provides a common interface to get management information for the thousands of different devices made by thousands of vendors. Each product may have it’s own management program but what if you want a dashboard with many different devices on one web page? Once you master SNMP every device looks the same. (In other words, all metric collection problems look like nails so SNMP is the metaphorical hammer) It’s a standard and there are MANY free tools
  • 12. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP The Lingo MIB – Management Information Base – A vendor provided file that explains what SNMP functionality they support. OID – Object Identifier – This is a specific variable that you can get or set on a device. MIB Namespace – A hierarchy that explains how an OID is determined. (picture coming in a few slides) Community – Password (RO = read-only, RW=read-write)
  • 13. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP The Lingo Cont. Get – Asking the device for a value Set – Changing a value in a device Trap – A device sending out an alert Manager – Your PC Agent – The device you’re monitoring

  • 17. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP What you need to use SNMP The bare minimum to get started: – A SNMP querying program – IP address of the device – Community name – The OID Extras: – Device MIBs (yes… you don’t need MIBs to query a device) – A cool GUI – SNMP Trap receiver

Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP Setting up Domino for SNMP http://www-01.ibm.com/support/docview.wss?uid=swg21169283 or IBM Domino Administrator 9.0.1 Social Edition Help Look for “Configuring the Domino SNMP Agent” (OS specific steps) Steps for setup on Windows OS 1. Configure SNMP at the Windows operating system level – Go to Start --> Settings --> Control Panel --> Add/Remove Programs. – Select "Add/Remove Windows Components" on the left. – Choose "Management and Monitoring Tools" and click "Details". – Select all under "Management..." – Reboot the operating system 2. Start Domino
  • 27. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP Setting up Domino for SNMP (continued) 3. Configure the Domino LNSNMP agent to run as a service: – Run the following commands in the Domino program directory. First stop the service if it is already running - in a DOS prompt run commands : c:Lotusdominonet stop lnsnmp c:Lotusdominonet stop snmp NOTE: If the service is not already running you may see the error: System error 1060 has occurred. The specified service does not exist as an installed service. c:LotusdominoLNSNMP -Sc ( this command is case sensitive ) If it starts you will see : Service creation complete
  • 28. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP Setting up Domino for SNMP (continued) 3. Continued – More commands to run… c:Lotusdominonet start snmp c:Lotusdominonet start lnsnmp If it starts you will see: The Lotus Domino SNMP Agent service was started successfully. (NOTE: SNMP console appears on server machine) 4. Run these commands on Domino server console load quryset load intrcpt (for SNMP traps) load collect 5. Add quryset and/or intrcpt and collect to ServerTasks (NOTES.INI)

  • 39. Homebrew your own Metrics: An IBM Domino Administrator's Guide to SNMP Troubleshooting A few quick things to check if you have problems talking to devices: – Double-check the community (case counts… it’s a password) – Double-check the IP address (ping it) – Double-check that SNMP is Enabled on the device (often it’s disabled by default) – Double-check that there isn’t any restrictions from where the device accepts SNMP packets from – Double-check the SNMP version. Version 1 or 2c are the most common and compatible. Version 3 uses advanced authentication and may be overkill so stick with 1 or 2c.
