This section describes the primary statistics gathered by <%=vars.product_name%> when statistics are enabled.
All statistics gathering requires the `gemfire.properties` `statistic-sampling-enabled` in `gemfire.properties` file to be true. Statistics that use time require the `gemfire.properties` `enable-time-statistics` to be true.
Performance statistics are collected for each Java application or cache server that connects to a cluster.

## <a id="section_DEF8D3644D3246AB8F06FE09A37DC5C8" class="no-quick-link"></a>Cache Performance (CachePerfStats)
Statistics for the <%=vars.product_name%> cache. These can be used to determine the type and number of cache operations being performed and how much time they consume.
Regarding <%=vars.product_name%> cache transactions, transaction-related statistics are compiled and stored as properties in the CachePerfStats statistic resource. Because the transaction’s data scope is the cache, these statistics are collected on a per-cache basis.
The primary statistics are:
| Statistic | Description |
|----------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| `compressTime` | Total time, in nanoseconds, spent compressing data. |
| `conflatedEvents` | The number of events that were conflated, and not delivered to event listeners or gateway senders on this member. Events are typically conflated because a later event was already applied to the cache, or because a concurrent event was ignored to ensure cache consistency. Note that some members may discard an update while other members apply the update, depending on the order in which each member receives the update. For this reason, the `conflatedEvents` statistic will differ for each <%=vars.product_name%> member. See [Consistency for Region Updates](../developing/distributed_regions/region_entry_versions.html#topic_CF2798D3E12647F182C2CEC4A46E2045). |

| `postCompressedBytes` | Total number of bytes after compressing. |
| `preCompressedBytes` | Total number of bytes before compressing. |

These statistics track status on partitioned region data copies. The primary statistics are:
<table>
<colgroup>
<col width="50%" />
<col width="50%" />
</colgroup>
<thead>
<tr class="header">
<th>Statistic</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr class="odd">
<td><code class="ph codeph">actualRedundantCopies</code></td>
<td>The least current redundant number of copies for any data in this partitioned region (there may be some data that is fully redundant, but some data will have only this number of copies). This value may drop when a data store is lost or rise when a data store is added. This value may drop temporarily during partitioned region creation or destruction and then rise again.
<div class="note note">
<b>Note:</b>
<p>If this value remains low, then partitioned region data is at risk and may be lost if another data store is lost.</p>
</div>
A healthy partitioned region will maintain a value equal to configuredRedundantCopies. The user should add one or more data stores if the value remains low. High-availability may result in a brief fluctuation, but it should return to a value equal to configuredRedundantCopies if there are sufficient data stores present (that is, killing one data store will cause its data to fail over to another data store).</td>
</tr>
<tr class="even">
<td><code class="ph codeph">configuredRedundantCopies</code></td>
<td>This is equivalent to the PartitionAttributes.getRedundantCopies configuration that was used to create this partitioned region. This value remains unchanged for a given partitioned region.</td>
</tr>
<tr class="odd">
<td><code class="ph codeph">lowRedundancyBucketCount</code></td>
<td>The number of buckets in this partitioned region that currently have fewer copies than the configuredRedundantCopies. This value may rise above zero when a data store is lost and return to zero when one or more data stores are added. This value may rise temporarily during partitioned region creation or destruction and then return to zero.
<div class="note note">
<b>Note:</b>
<p>If this value remains above zero, then partitioned region data is at risk and may be lost if another data store is lost.</p>
</div>
This value will be above zero whenever actualRedundantCopies is less than configuredRedundantCopies. A healthy partitioned region will maintain a value of zero. The user should add one or more datstores if this value remains above zero. High-availability may result in a brief fluctuation, but it should return to zero if there are sufficient data stores present (that is, killing one data store will cause its data to fail over to another data store).</td>
