Description
Accessing Robots.Txt File Both R The total count of current requests for
robots.txt. Every system requests for robots.txt implicitly, for every host, through HTTP.
Active Queue Length Both M The total count of documents which are
waiting for the robot threads. If this count is not 0, all threads should be filtering.

Description
Accessing Robots.Txt File Both R The total count of current requests for
robots.txt. Every system requests for robots.txt implicitly, for every host, through HTTP.
Delayed Documents Both M The total count of documents delayed
because of the site hit frequency rules.
Document Entries Both M The total count of document entries
currently in memory. The count zero indicates that no indexing activity is going on.
Documents Delayed Retry 2007 M The total count of documents that are
retried after time-out. When this is non-zero, it means that the local server it is crawling is shut down.
Documents Filtered Both F The total count of times when a filter
object was created. This correlates to the total count of documents filtered in the system since startup.
Documents Filtered Rate Both M The total count of documents filtered per
second. Documents Successfully
Filtered
Both F The total count of documents which are
successfully filtered. Documents Successfully
Filtered Rate
Both R The total count of documents successfully
filtered per second.
Ext. Notifications Rate 2007 F The rate at which the external
notifications are being received per second.
Ext. Notifications Received 2007 F The total count of notifications which are received from all notification sources excluding file system.
Filter Objects Both F The total count of filter objects in the
system. Each filter object correlates to a URL currently being filtered.
Filter Processes Created Both M The total number of times a filter process
was created or restarted. Occurrence of too many filter processes denotes there is trouble in filtering of the data in the documents.

Description
Accessing Robots.Txt File Both R The total count of current requests for
robots.txt. Every system requests for robots.txt implicitly, for every host, through HTTP.
Filter Processes 2007 F The total count of filtering processes in
the system.
Filter Processes Max 2007 F The maximum number of filtering
processes that dwell in the system since startup.
Filtering Threads Both M The total count of filtering threads in the
system. This number is computed based on your system resources.
Heartbeats Both F The total count of heartbeats counted
since startup. A heartbeat occurs once in every 10 seconds while the service is running. If the service stops running, there are no heartbeats, and the count of ticks does not go up.
Heartbeats Rate Both R Shows one heartbeat in every 10 seconds.
Idle Threads Both R The total count of threads which are
waiting for documents.
Notification Sources 2007 F The external notification sources which
are currently connected.
Notifications Rate 2007 R The rate of external notifications received
per second.
Performance Level Both M Denotes the level of the amount of system
resources that the Gatherer service is allowed to use.

Description
Accessing Robots.Txt File Both R The total count of current requests for
robots.txt. Every system requests for robots.txt implicitly, for every host, through HTTP.
Reason to back off 2007 R The code that describes why the Gatherer
service went into back off state. 0 - up and running
1 - high system IO traffic 2 - high notifications rate
3 - delayed recovery in progress (not implemented)
4 - back off due to user activity 5 - Battery Low
6 - Memory Low
99 - back off for some internal reason (forced by Search itself)
While backing off, indexing stops. You must eliminate the reason for back off to resume indexing. If the Gatherer service is in back off state, the Search service is paused, and the event log shows up a message.
Robots.Txt Requests Both F The total count of requests for robots.txt.
Server Objects Both F The total count of servers which the
system recently accessed.
Server Objects Created Both F The total count of times when a server
object had to be created. Servers Currently
Unavailable
Both M The number of servers that are
unavailable due to requests that have timed out.
Servers Unavailable Both R The number of servers that are
unavailable due to requests that have timed out.
Stemmers Cached Both R The total count of available cached
stemmer instances. Too many instances may hint at a resource usage problem.

the back off logic detects. Threads Accessing
Network
Both M The total count of threads waiting for a
response from the filter process. If no activity occurs and this count equals the count of filtering threads, the following conditions are indicated:
■ A network problem
■ Unavailability of the server on which it is crawling.

2007 M The total count of threads blocked
because of the back off event.
Threads In Plug-ins Both R The total count of threads waiting for
