NAME

rdbmsmond - HA Database MIB Monitor daemon

SYNOPSIS

rdbmsmond [-l][-h hostname ][

-p portnumber ][-t timeout ][-r retries ][-c community ][

-d]

DESCRIPTION

The

rdbmsmond daemon is used to monitor the Relational Database Management System MIB for the

Event Monitoring Service (EMS) using SNMP. The daemon can monitor either a local or a remote MIB.

rdbmsmond includes a resource dictionary ﬁle which is used by the Event Monitoring Service to identify

resources for monitoring.

Options

rdbmsmond recognizes the following command-line options:

-l Write a syslog message every time SNMP is queried for a monitored resource value.

-h Perform SNMP queries against hostname . By default the local system is queried to get the

contents of the MIB.

-p Perform SNMP queries against portnumber . This option is useful when querying proxy

SNMP agents. By default SNMP queries are directed against the SNMP port (161).

-t Wait timeout seconds before retransmitting SNMP requests. By default 5 seconds will

expire between retransmissions.

-r Attempt to retransmit SNMP requests retries number of times before considering the host

unreachable. The default is to retransmit 1 time.

-c The community string to use with the SNMP requests. The string "public" is used by

default.

-d Turn on internal daemon debugging messages. This logs additional information to the ﬁle

/var/opt/resmon/log/rdbmsmond.log

WARNING: This ﬁle grows without bound. Only use this option if you really need a trace.

RESOURCES

The HA Database MIB Monitor monitors the following resources:

Server Status

(

/rdbms/server/status/

<servername>)

The state of the database server. Possible values are:

UP The server is operational and available for processing requests

DOWN The server is not available for processing requests.

HALTED The server is temporarily unavailable for administrative reasons.

CONGESTED The server is not accepting requests due to resource limitations.

RESTARTING The server has been restarted and will be available soon.

Server Connections

(

/rdbms/server/connects/<servername>)

The current number of simultaneous connections to the database server.

Server Uptime

(

/rdbms/server/uptime/<servername>)

The length of time, in seconds, that the database server has been running. A value of zero might indicate

that the database server started before the database SNMP subAgent.

Server Started

(/rdbms/server/started/<servername>)

The date and time when the database server was last started, in the format YYYY/MM/DD HH:MM:SS.S.

The daemon can monitor either a local or a remote MIB.
PAGE 2
rdbmsmond(1) rdbmsmond(1) Server Disk Reads (/rdbms/server/disk_reads/) The number of physical reads done by the database server. Server Disk Reads Per Second (/rdbms/server/disk_reads_per_sec/) The number of physical reads per second done by the database server. Server Logical Reads (/rdbms/server/logical_reads/) The number of logical reads done by the database server.
PAGE 3
rdbmsmond(1) rdbmsmond(1) The ratio of logical writes less physical writes to logical writes, done by the database server. This is a measure of the effectiveness of the disk write cache. It is a floating-point number, expressed as a percentage. A value of 100 would imply that all writes are from the cache; in other words, the closer to 100, the better the performance. A value of -1 implies that no logical writes have occurred.

rdbmsmond(1) rdbmsmond(1) /var/opt/resmon/log/rdbmsmond.log Debug log file. If the -d option is specified, internal debug trace messages are written to this file. DEPENDENCIES rdbmsmond must be run by the registrar process of the Event Monitoring Service (EMS). The SNMP Master Agent (snmpd) and the appropriate database subAgents must be running. For more information about these daemons, see snmpd(1M) and the appropriate documentation for the database that is being monitored.
