Event Management | Collecting Events and Metrics


In the previous video in this series, we saw an overview of ITOM Event Management and Operational Intelligence. This video describes the process of collecting events for Event Management, and collecting metrics for Operational Intelligence. Event Management and Operational Intelligence receive events and metrics from external sources in two ways. ServiceNow connectors running on MID Servers
pull events and metrics from external sources and send them to the ServiceNow instance. And external sources can push their event and metric data to ServiceNow listeners on MID Servers and the instance. First, let’s look at pulling events through connectors. To collect events, Event Management sends requests for specific sources to connectors on a MID Server. The connectors send requests to the sources. The sources return events to the connectors… …and the connectors forward the events to Event Management. ServiceNow supplies connectors to pull standard events from sources like SCOM, SolarWinds, and lots more. You’ll need to configure these connectors
to pull events from specific sources on the network. You can also create custom connectors to pull events from external sources by making calls to APIs on the sources. Now let’s look at collecting events that
are pushed to Event Management. There are a few different ways to collect pushed events. Listeners on MID Servers can collect events
using Web Services or SNMP. This is how you’d collect events from Oracle
Enterprise Manager or BMC TrueSight. You’ll need to configure the source to send
events to the MID Server’s IP address… … and to the correct port for Web Services or SNMP. You can also collect events using a Web Services
listener on the instance. This is how you’d collect events from AWS
or Azure. You’ll need to configure the source to send
events to the instance name. Sources can even send events directly to the
instance by email. And finally, for a source that sends events
in its own format… … you can add a transform script to transform those events to ServiceNow event format. Now let’s look at how Operational Intelligence
collects metrics. It’s pretty similar to how Event Management collects events… … except that all the collection is done on the OI MID Servers. The instance isn’t involved. Connectors running on MID Servers send requests
to data sources on your network… …and the sources return metrics to the connectors. And listeners on MID Servers receive metrics
pushed by sources on your network. ServiceNow supplies connectors to pull metrics from sources like SCOM, SolarWinds, AWS, Azure, and others. You’ll need to configure these connectors
to pull metrics from specific sources on the network. You can also create custom connectors to pull
metrics from external sources. And finally, you can configure an OI MID Server
as a Web Services listener to receive metrics pushed by external sources. You’ll need to configure the source to send
metrics to the MID Server’s IP address. In our next video, we’ll look at event rules. For more information, please consult our product
