Host Template: Cloud - Azure - Redis
Overview Copied
Azure Redis Cache is based on the popular open source Redis Cache. It gives you access to a secure, dedicated Redis Cache, managed by Microsoft and accessible from any application within Azure. Azure Redis Cache is available in a variety of tiers, (i.e. Basic, Standard, Premium), offering an expanded set of throughput and consistent low-latency data access to power fast, scalable Azure applications.
This Host Template includes the following Service Checks:
Service Check Name | Description | Default Thresholds (Metric: Warning, Critical) | UOM |
---|---|---|---|
Azure - Redis - CPU Usage | The CPU usage as a percentage [Default Timespan = 5mins, Default Check Interval = 5mins] |
percent_processor_time: |
% |
Azure - Redis - Cache Bytes | The number of cache read and write bytes per second [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | B/s |
Azure - Redis - Cache Requests | The number of cache hits and misses [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | N/A |
Azure - Redis - Commands | The number of commands processed [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | N/A |
Azure - Redis - Connected Clients | The maximum number of connected clients [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | N/A |
Azure - Redis - Keys | The number of keys [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | N/A |
Azure - Redis - Memory Usage | The memory usage as a percentage [Default Timespan = 5mins, Default Check Interval = 5mins] |
used_memory_percentage: |
% |
Azure - Redis - Memory Used Ratio | The ratio of memory allocated to Redis to memory being used by Redis [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | N/A |
Azure - Redis - Memory Used | The memory allocated to Redis (RSS) and used by Redis [Default Timespan = 5mins, Default Check Interval = 5mins] |
N/A | B |
Azure - Redis - Server Load | The maximum percentage load on the server [Default Timespan = 5mins, Default Check Interval = 5mins] |
server_load: |
% |
Note
The “Default Timespan” given for these Service Checks refers to the time period we use when retrieving metrics from Azure.

Dynamic Thresholds Support Copied
Some Service Checks within this Host Template support Dynamic Thresholds for Opsview Enterprise.
Prerequisites for monitoring Copied
Provide Subscription Access Copied
To use this Host Template you will need to provide access to the subscription you wish to monitor. Navigate to the Subscriptions section and select your Subscription.
In the Subscription to be monitored, click Access Control (IAM).
Then click the Add button, select the required role and select the application, once for each of the following roles:

Repeat these steps for each subscription you wish to monitor.
Usage Instructions Copied
Please review the overall Cloud - Azure Opspack documentation for details on prerequisites, known issues, and other necessary configurations that apply to all Host Templates in the Opspack.
Add this Host Template Copied
Add the Cloud - Azure - Redis Host Template to your Opsview Monitor host. If the resource you’re monitoring has no hostname or public IP, then open the Advanced settings pane and change Host Check Command to Always assumed to be UP.
Note
For more information, refer to the documentation on Adding Host Templates to Hosts.
Add and configure Variables Copied
The Service Checks in this Host Template use the following variables, and they will be added to your Opsview Monitor instance alongside the Host Template:
