How to Monitor Domino Application Server using eG Enterprise?

eG Enterprise monitors the Domino application server in both agent-based and agentless manners. This chapter discusses about how to configure and manage the Domino Application server to work with eG manager.

Enabling SNMP on a Domino Server

Domino SNMP Agent services are provided by two types of programs:

LNSNMP - The Lotus Notes SNMP agent. As an independent application, LNSNMP is insulated from most Domino server malfunctions and, by itself, adds negligible overhead to the server.
Two Domino server add-ins - the QuerySet Handler and the Event Interceptor.

The QuerySet Handler and the Event Interceptor depend on the Domino server; if the server fails for any reason, these programs fail as well.

The following components comprise the Domino SNMP Agent architecture:

A platform-specific Master SNMP Agent - An independent, non-Lotus, agent usually supplied with the operating system platform that provides SNMP services for the machine. This SNMP Agent transports the SNMP traps and Get/Set responses across the network to the management station.
The Domino SNMP Agent consisting of:
- LNSNMP Agent - The Lotus Notes SNMP agent, which receives trap notifications from the Event Interceptor and then forwards them to the management station using the platform-specific SNMP Agent. LNSNMP also handles requests for Domino-related information from the management station by passing the request to the QuerySet Handler and responding back to the management station.
- QuerySet Handler - Which queries server statistics information, sets the value of configurable Domino-based parameters, and returns Domino statistics information to LNSNMP, which then forwards the information to the management station using the platform-specific master SNMP Agent.
- Event Interceptor - Which responds to the SNMP Trap notification for Domino Event Handlers by instructing LNSNMP to issue a trap.
The Domino MIB - A standard Management Information Base (MIB) file for Lotus Domino servers that can be compiled and used by a network management program such as eG Enterprise.

Enabling SNMP for a Domino Server on Solaris

To enable SNMP on a Domino server on Solaris, follow the broad steps given below:

Install the Master SNMP agent on the Domino server
Configure the Domino SNMP agent to communicate with the Master SNMP agent

Each of these steps has been discussed in great detail below.

Installing and Configuring the Master SNMP Agent on the Domino Server

On Solaris platform, the Domino SNMP Agent uses the SMUX protocol, per RFC 1227, to communicate with the system's Master SNMP Agent. The Solaris Master SNMP Agent does not support the SMUX protocol, making it necessary to substitute a Master SNMP Agent that does. On Solaris platforms, Domino includes a suitable NET-SNMP Master Agent, called NET-SNMPD, already configured to support the SMUX protocol and the Domino SNMP Agent.

Note:

Before using NET-SNMPD, disable any existing Master SNMP Agent. Please follow the steps below for disabling an existing Master SNMP Agent running on Solaris.

Log in as root.
Stop the snmpdx daemon by typing, /etc/rc3.d/S76snmpdx stop.
Disable the snmpdx daemon by issuing the command, mv /etc/rc3.d/S76snmpdx /etc/rc3.d/s76snmpdx.

To use the NET-SNMPD that is provided with Domino, do the following:

Login as the root user.
Next, install the NET-SNMPD files. Enter this command, changing the Domino executable path if necessary: cp /opt/lotus/notes/latest/sunspa/net-snmpd* /etc
Arrange for NET-SNMPD to be restarted after a reboot. Enter these commands:

ln -f -s /etc/net-snmpd.sh /etc/init.d/net-snmpd

ln -f -s /etc/init.d/net-snmpd /etc/rc2.d/S76net-snmpd

ln -f -s /etc/init.d/net-snmpd /etc/rc1.d/K76net-snmpd

After installation, proceed to configure and start NET-SNMPD. Here is how:

Update the /etc/net-snmpd.conf file with appropriate community names for your remote management infrastructure. Community names are set using the rocommunity and rwcommunity directives. For instance, to set a community named nppublic, the command would be: Set rocommunity value to nppublic

To manually start NET-SNMPD, login as the root user and issue the command, /etc/net-snmpd.sh start. To stop NET-SNMPD, use this command: /etc/net-snmpd.sh stop

Configuring the Domino SNMP Agent

The Domino SNMP Agent configuration on Solaris involves the following:

Configuring the LNSNMP agent to work with the Master SNMP Agent that is provided with the Domino server on Solaris
Completing the configuration by starting the add-in tasks

Before attempting to configure the Domino SNMP agent, ensure the following:

The Solaris Master SNMP Agent provided with Domino should be properly installed and configured on the server. Refer to the steps discussed in Installing and Configuring the Master SNMP Agent on the Domino Server for the procedure.
TCP/IP and SNMP should be properly installed and configured on the server. Ensure that the Domino executable and the Domino data directories are in your search path.
The Domino SNMP Agent is set up to run automatically. Once the Domino SNMP Agent is configured, it is virtually always running, even when Domino is not. If you later upgrade Domino, stop the LNSNMP process, before beginning the upgrade process.

To configure the LNSNMP agent, do the following:

Login as the root-user.
Stop the LNSNMP process. Enter this command: lnsnmp.sh stop
Stop the NET-SNMP Master Agent by entering this command: /etc/net-snmpd.sh stop
Start the NET-SNMP Master Agent by entering this command: /etc/net-snmpd.sh start
Start the LNSNMP process using the command, lnsnmp.sh start
Create a link to the LNSNMP script. Enter this command, changing the Domino executable path if necessary: ln -f -s /opt/lotus/notes/latest/sunspa/lnsnmp.sh /etc/init.d/lnsnmp
Arrange for LNSNMP to be restarted after a reboot. Enter these commands:

ln -f -s /etc/init.d/lnsnmp /etc/rc2.d/S77lnsnmp

ln -f -s /etc/init.d/lnsnmp /etc/rc1.d/K77lnsnmp

After configuring the LNSNMP agent, start the Domino server add-in tasks such as the QuerySet, Event Interceptor, and Statistic Collector tasks. To achieve this, do the following:

To support SNMP queries, start the QuerySet add-in task. Enter this command on the Domino Server console: load quryset
To support SNMP traps for Domino events, start the Event Interceptor add-in task. Enter this command on the Domino Server console: load intrcpt
To support Domino statistic threshold traps, start the Statistic Collector add-in task. Enter this command on the Domino Server console: load collect
Arrange for the add-in tasks to be restarted automatically when Domino is next restarted. Add quryset and/or intrcpt and collect to the ServerTasks variable in Domino’s notes.ini file.

ServerTasks =Update,Replica,Router,Amgr,AdminP,CalConn,Sched,LDAP,quryset,intrcpt,collect

Enabling SNMP for a Domino Server on Linux

To enable SNMP on a Domino server on Linux, follow the broad steps given below:

Install the Master SNMP agent on the Domino server
Configure the Domino SNMP agent to communicate with the Master SNMP agent

Each of these steps has been discussed in great detail below.

Installing and Configuring the Master SNMP Agent on the Domino Server

Like the Solaris platform, on Linux also the Domino SNMP Agent uses the SMUX protocol, per RFC 1227, to communicate with the system's Master SNMP Agent. Some Linux distributions include a Master SNMP Agent that supports the SMUX protocol; others do not. On Linux platforms, Domino includes a suitable NET-SNMP Master Agent, called NET-SNMPD, already configured to support the SMUX protocol and the Domino SNMP Agent.

Note:

Before using NET-SNMPD, disable any existing MasterSNMP Agent. For information on disabling an existing Master SNMP Agent, see your Master SNMP Agent's documentation.

To use the NET-SNMPD that is provided with Domino, do the following:

Login as the root user.
Next, install the NET-SNMPD files. Enter this command, changing the Domino executable path if necessary: cp /opt/lotus/notes/latest/linux/net-snmpd* /etc
Arrange for NET-SNMPD to be restarted after a reboot. Enter these commands:

ln -f -s /etc/net-snmpd.sh /etc/rc.d/init.d/net-snmpd

chkconfig --add net-snmpd

chkconfig net-snmpd on

After installation, proceed to configure and start NET-SNMPD. Here is how:

To manually start NET-SNMPD, login as the root user and issue the command, /etc/net-snmpd.sh start. To stop NET-SNMPD, use the command, /etc/net-snmpd.sh stop.

Configuring the Domino SNMP Agent

The Domino SNMP Agent configuration on Linux involves the following:

Configuring the LNSNMP agent to work with the Master SNMP Agent that is provided with Domino on Linux
Completing the configuration by starting the add-in tasks

Before attempting to configure the Domino SNMP agent, ensure the following:

The Linux Master SNMP Agent provided with Domino should be properly installed and configured on the server. Refer to the steps discussed in Installing and Configuring the Master SNMP Agent on the Domino Server for the procedure.
TCP/IP and SNMP should be properly installed and configured on the server. Ensure that the Domino executable and the Domino data directories are in your search path.
The Domino SNMP Agent is set up to run automatically. Once the Domino SNMP Agent is configured, it is virtually always running, even when Domino is not. If you later upgrade Domino, stop the LNSNMP process, before beginning the upgrade process.

To configure the LNSNMP agent, do the following:

Login as the root-user.
Stop the LNSNMP process. Enter this command: lnsnmp.sh stop
Stop the NET-SNMP Master Agent by entering this command: /etc/net-snmpd.sh stop
Start the NET-SNMP Master Agent by entering this command: /etc/net-snmpd.sh start
Start the LNSNMP process using the command, lnsnmp.sh start.
Arrange for LNSNMP to be restarted after a reboot. Enter these commands:

ln -f -s /opt/lotus/notes/latest/linux/lnsnmp.sh /etc/rc.d/init.d/lnsnmp

chkconfig --add lnsnmp

chkconfig lnsnmp on

After configuring the LNSNMP agent, start the Domino server add-in tasks such as the QuerySet, Event Interceptor, and Statistic Collector tasks. To achieve this, do the following:

To support SNMP queries, start the QuerySet add-in task. Enter this command on the Domino Server console: load quryset
To support SNMP traps for Domino events, start the Event Interceptor add-in task. Enter this command on the Domino Server console: load intrcpt
To support Domino statistic threshold traps, start the Statistic Collector add-in task. Enter this command on the Domino Server console: load collect
Arrange for the add-in tasks to be restarted automatically when Domino is next restarted. Add quryset and/or intrcpt and collect to the ServerTasks variable in Domino’s notes.ini file.

ServerTasks =Update,Replica,Router,Amgr,AdminP,CalConn,Sched,LDAP,quryset,intrcpt,collect

Enabling SNMP for a Domino Server on AIX

To enable SNMP on an AIX Domino server, you will have to configure the Domino SNMP agent. This involves ensuring that the LNSNMP process communicates with the SNMPD subsystem (on the AIX installation of Domino) using the SMUX protocol.

However, prior to configuring the Domino SNMP agent, make sure that the following are in place:

TCP/IP and SNMP should be properly installed and configured on the server. Also, make sure that the Domino executable and the Domino data directories are in your search path
The trap destinations and community names for AIX should be appropriately configured in the /etc/snmpd.conf file for your remote management infrastructure. Remember to keep the view identifiers unique for each trap destination.
The Domino SNMP Agent is set up to run automatically. This means that once the Domino SNMP Agent is configured, it is virtually always running, even when Domino is not. If you later upgrade Domino you should stop the LNSNMP process before beginning the upgrade process.

Next, proceed to configure the Domino SNMP agent, using the procedure explained below:

Login as the root user.
Stop the LNSNMP process. Enter this command: lnsnmp.sh stop
Stop the SNMPD (SNMP Daemon) subsystem. The Simple Network Management Protocol (SNMP) daemon is a background server process that can be run on any Transmission Control Protocol/Internet Protocol (TCP/IP) workstation host. The daemon, acting as SNMP agent, receives, authenticates, and processes SNMP requests from manager applications. This daemon is installed and started by default on AIX systems. To stop SNMPD, enter this command: stopsrc -s snmpd
Configure SNMPD to accept LNSNMP as an SMUX peer. Add the following line to the /etc/snmpd.peers file: "Lotus Notes Agent" 1.3.6.1.4.1.334.72 "NotesPasswd"
Configure SNMPD to accept an SMUX association from LNSNMP. Add the following line to /etc/snmpd.conf: smux 1.3.6.1.4.1.334.72 NotesPasswd
Start the SNMPD subsystem. Enter this command: startsrc -s snmpd
Start the LNSNMP process. Enter this command: lnsnmp.sh start
Create a link to the LNSNMP script. Enter this command, changing the Domino executable path if necessary: ln -f -s /opt/lotus/notes/latest/ibmpow/lnsnmp.sh /etc/lnsnmp.rc
Arrange for LNSNMP to be restarted after a reboot. Add the following line to the end of the /etc/rc.tcpip file: /etc/lnsnmp.rc start

After configuring the LNSNMP agent, start the Domino server add-in tasks such as the QuerySet, Event Interceptor, and Statistic Collector tasks, using the procedure discussed in Configuring the Domino SNMP Agent .

Enabling SNMP for a Domino Server on Windows

To enable SNMP on a Windows Domino server, follow the broad steps given below:

Install the Windows SNMP service on the target host
Install the LNSNMP agent (i.e., the Lotus Domino SNMP agent) on the target host
Configure the Lotus Domino SNMP agent as a service on the target host

Each of these steps is discussed in great detail in the sections to come.

After Rebooting start the LNSNMP Service first

And then start the Domino Server.

Configuring the LNSNMP Agent

Prior to configuring the LNSNMP agent, ensure the following:

Before using the Domino SNMP Agent, make sure TCP/IP and SNMP are properly installed and configured on the server. Also, make sure that the Domino executable and the Domino data directories are in your search path.
If you need to add the Windows SNMP Service to your system, be prepared to reinstall any Windows service packs immediately after adding the Windows SNMP Service.
The Windows SNMP Service is configured by double-clicking the Network icon in the Control Panel, then selecting the Services tab, then selecting SNMP Service, and then clicking the Properties button. You will want to configure appropriate trap destinations and community names for your remote management infrastructure.
The Domino SNMP Agent is configured as a Windows Service and is set up to run automatically. This means that once the Domino SNMP Agent is configured, it is virtually always running, even when Domino is not. If you later upgrade Domino you should stop the LNSNMP and Windows SNMP Services before beginning the upgrade process.

To configure the LNSNMP agent, do the following:

Stop the LNSNMP and SNMP services. Enter these commands:

net stop lnsnmp

net stop snmp
Configure the Lotus Domino SNMP Agent as a service. Enter this command: lnsnmp -Sc
Start the SNMP and LNSNMP services. Enter these commands:

net start snmp

net start lnsnmp
