SMTP Platform Service

Topics marked with * relate to features available only in vFabric Hyperic.

Monitoring a Remote SMTP Service

Hyperic can monitor an SMTP service over the network. You configure a platform service of type "SMTP" on the operating system platform of your choice. The Hyperic Agent on that platform collects the metrics for the remote service and presents them under the newly created platform service.

Resource Plugin, Functions, and Classes

The SMTP service type is managed by Hyperic's netservices plugin. The plugin performs the following functions:

  • Metric collection using the org.hyperic.hq.plugin.netservices.SMTPCollector class.

  • Event tracking using the reportEvent method in the Collector class.

Configure the SMTP Service in Hyperic

The "SMTP" service type must be manually configured.

  1. Navigate to the platform whose Agent will monitor the service.

  2. Select New Platform Service from the Tools menu.

  3. On New Service page, enter a name for the service and select "SMTP" from the Service Type pull-down.

  4. Supply all required values on the Configuration Properties page. Configuration options are defined below in SMTP Configuration Options.

Configuration Properties Page

The Configuration Properties page for the SMTP service type is shown below.

SMTP Configuration Options

The tables below define the options in the configuration schema for the "HTTP" service type. These are the resource attributes that are displayed, and may be edited, on the Configuration Properties page for an SMTP service, shown above.

Note: For the SMTP service type, the netservices plugin sets value of:

  • port to 25

  • sslport to 250

SMTP Metrics

  • Availability - The agent reports an SMTP service available if it can connect to it and read the welcome banner.

  • Connection Metrics

    • All Inbound Connections - Number of inbound connections of all types to the service.

    • All Outbound Connections - Number of outbound connections of all types from the service.

    • Inbound Connections - Number of inbound TCP connections to the service.

    • Outbound Connections - Number of outbound TCP connections from the service.

  • Response Time - The time (in ms) it took to determine service availability.

  • TCP connection state metrics - The number of connections in each connection state is reported:

    • CLOSE_WAIT

    • CLOSED

    • ESTABLISHED

    • FIN_WAIT_1

    • FIN_WAIT_2

    • LAST_ACK

    • LISTEN

    • SYN_RECEIVED

    • SYN_SEND

    • TIME_WAIT

For definitions of TCP connection states, see RFC 793.

SMTP Monitoring Defaults Page

You can enable and disable metrics, select indicator metrics, and change the collection interval for a resource type on its Monitoring Defaults page. To navigate to a resource type's Monitoring Defaults page:

  1. Click the Administration tab.

  2. Click Monitoring Defaults.

  3. Scroll down to the resource type and click Edit Metric Template.

The Monitoring Defaults page for the SMTP service type is shown below:

Event Tracking

You can enable log tracking for a network service. If you do, the agent will log an event for responses that match the criteria you specify.

To enable log tracking, click the Enable Log Tracking box in the Monitoring section of the Configuration Properties page.

For information about Hyperic log tracking functionality and configuration options, and how to view log events, see Set Up Log Tracking for a Resource.
