Measurement
Unit |
Interpretation |
| App_enumerations |
Represents
the number of application enumerations per second |
Enums/Sec
|
The Citrix Program Neighborhood allows a user to
get a listing of all available applications published in the farm.
This enumeration of resources takes place automatically every time
the user launches the Citrix Program Neighborhood. This metric reflects
the rate of application enumerations. An unusually high number of
enumerations can slow down a Citrix server.
|
| App_resolutions |
Represents
the number of application resolutions per second |
Resolutions/sec
|
When the user clicks the link to a published application, the link is resolved to an application. This metric reflects the workload on the
server in terms of application accesses. The rate of application resolutions
depends on the number of users connecting to the farm, duration for which
the average user stays logged on, and the number of published applications.
If the rate of application resolutions is excessively high, consider
creating multiple zones in the farm to reduce the load on the data collector.
|
| Dstore_conn_failure |
Indicates the duration (in minutes) for which the Citrix server has been disconnected from the data store
|
Mins |
The data store of a Citrix
MetaFrame XP server hosts
centralized configuration data for
a server farm. The data store is
critical for central administration
of the server farm. Hence, any
loss of communication between a
Citrix server and its data store
can result in inconsistencies in
the configuration data.
|
| Dstore_read_rate |
The
rate of data read from the IMA data store |
KBytes/Sec |
This metric reports the workload on the data store. Since it is
a central repository for a farm,a slowdown of the data store can impact
the performance of the farm. Data store traffic is usually high during
server startup.
|
| Dstore_write_rate |
The
rate of data written into the IMA data store |
KBytes/Sec |
This metric reports the workload on the data store. Since it is
a central repository for a farm,a slowdown of the data store can impact
the performance of the farm.
|
| Dynstore_read_rate |
The
rate of data read from the IMA Dynamic store |
KBytes/Sec |
The dynamic store maintains information that changes frequently
such as current sessions, disconnected sessions, server load, etc. This metric denotes
the read rate of data from the dynamic store. |
| Dynstore_write_rate |
The
rate of data written into the IMA Dynamic store |
KBytes/Sec |
The dynamic store maintains information that changes frequently
such as current sessions, disconnected sessions, server load, etc. This metric denotes
the rate at which data is written to the dynamic store. |
| LH_cache_read_rate |
The
rate of data read from the IMA Local Host Cache |
KBytes/Sec |
Each server has a subset of the data store called the local host cache.
The local host cache performs two functions:
-
It permits the server to function in the absence of a connection to the data store.
- Improves performance by caching information used by ICA clients for
enumeration and application resolution.
The larger the cache, greater the hits to the cache and fewer data store
accesses. Comparing the read rate from the local host cache and the data
store, the administrator can assess the cache efficiency.
|
| LH_cache_write_rate |
The
rate of data written into the IMA Local Host Cache |
KBytes/Sec |
|
| Zone_elections |
Indicates
the number of zone elections that have occurred |
Number |
Zones in a Citrix farm serve two purposes - (a) to collect data from member servers
in a hierarchical structure; (b) efficiently distribute changes to all servers
in the farm. The first server in a farm is the data collector of the farm by
default. Elections within a zone are used to determine the data
collector for the zone. Frequent zone elections in a zone can result
in increased network traffic.
|
| Zone_elections_won |
Indicates
the number of times a Citrix server has won a zone election |
