# Agent Client Collector upgrade properties

System properties that control Agent Client Collector upgrade behavior, including the target version, rate limits, retry logic, and timeouts.

## Selective upgrade properties

Set these properties before running any selective upgrade. Navigate to **All** > **System Properties** > **All Properties** and search for each property name.

|Property|Value|Description|
|--------|-----|-----------|
|**sn\_agent.auto\_upgrade.enabled**|`true`|Enables the upgrade feature. Set to **true** before running any upgrade, manual or scheduled.|
|**sn\_agent.agent\_upgrade\_version**|Target version, for example `5.0.1`|The version agents upgrade to. If empty, the system uses the current Agent Client Collector Framework application version. Must be a valid version number.|

## Optional properties

These properties have default values suitable for most environments. Adjust them only when your environment requires different rate limits or timeout thresholds.

|Property|Default|Description|
|--------|-------|-----------|
|**sn\_agent.auto\_upgrade.max\_upgrades\_per\_hour**|1000|Maximum agents upgraded per job run across all MID Servers. Lower this value for a more gradual rollout pace.|
|**sn\_agent.auto\_upgrade.max\_upgrades\_per\_handler\_per\_hour**|50|Maximum agents upgraded through a single MID Server per job run. Prevents overloading individual MID Servers.|
|**sn\_agent.auto\_upgrade.retry\_limit**|3|Number of times the system retries a failed upgrade before permanently skipping the agent. After an agent reaches this limit, reset the `failed_upgrade_attempts` field on the Agent Extended Info record to allow retries.|
|**sn\_agent.agent\_upgrade\_wait\_time**|30|Minutes the system waits for an agent to complete its upgrade before marking it as failed and transitioning the agent to **Warning** status.|
|**sn\_agent.upgrade.timeout\_minutes**|10|Minutes allowed for the initial upgrade validation check on the agent \(AgentVerification stage\).|
|**sn\_agent.min\_upgrade\_history\_per\_agent**|2|Number of upgrade history records retained per agent. Older records are automatically removed.|

## Property usage note

The **sn\_agent.agent\_upgrade\_version** property is specifically for overriding the upgrade target version. The **sn\_agent.agent\_version** property controls package download URLs, version display, and other system behaviors. Use **sn\_agent.agent\_upgrade\_version** when you want to target a specific version for upgrades without affecting other system behavior.
