+title: Cache Health Check
+pageTitle: django-health-check cache check
+description: Verify that the Django application's caching system is operating seamlessly and efficiently
+---
+
+Caching is storing the outcome of a time-consuming calculation to avoid recomputing in the future.
+
+The `health_check.cache` verifies that the Django application
+caching mechanism is functioning as intended.
+
+
+## Settings
+
+The settings that need to be correct are the standard Django `CACHES`
+settings in your `settings.py`.  
+To ensure that you have configured Caching properly go through this 
+[documentation](https://docs.djangoproject.com/en/4.2/topics/cache/)
+
+## What does it check?
+
+This check does the following:
+
+- Reads the cache backend's configuration
+- Writes to the cache backend
+- Reads from the cache backend
+- Checks for timeouts
+- Deletes the test data from the cache backend
+- Returns status 
+
+This ensures your app's cache backend is functioning correctly and is always available. It not only prevents [data inconsistencies](https://www.alachisoft.com/blogs/cache-database-data-inconsistency-pitfall-and-solutions/#:~:text=Data%20inconsistency%20issues%20occur%20when,the%20cache%20is%20not%20synchronized) and [race conditions](https://www.techtarget.com/searchstorage/definition/race-condition) but also helps identify and troubleshoot cache-related problems.
+
+## Steps
+1.Installation
+ ```shell
+#requirements.txt
+django-health-check == x.x.x
+```
+
+2.Configure your health check URL endpoint:
+
+```python
+urlpatterns = [
+    # ... your existing URLs here ...
+    url(r'^health/', include('health_check.urls')),
+]
+```
+
+3.Add the `health_check.cache` applications to your `INSTALLED_APPS`:
+
+```python
+INSTALLED_APPS = [
+    # ...
+    'health_check',                             
+    'health_check.cache',
+]
+```
+4.The cache healthcheck tries to write and read a specific key within the cache backend. 
+It can be customized by setting `HEALTHCHECK_CACHE_KEY` in the `settings.py` file to another value:
+
+```python
+HEALTHCHECK_CACHE_KEY = "custom_health_check_key"
+```
+
+5.Run the health check
+```shell
+python manage.py health_check
+
+```

+## Settings
+
+The settings that need to be correct are  `HEALTHCHECK_CELERY_RESULT_TIMEOUT`
+and `HEALTHCHECK_CELERY_QUEUE_TIMEOUT` in your `settings.py`.  
+
+## What does it check?
+
+This check does the following:
+
+- Checks celery worker status 
+- Checks that the celery workers can execute tasks
+- Results are returned within specified time limits
+
+Celery health checks helps you catch potential issues early, ensures proper configuration, 
+and provides insights into the real-time status of your Celery workers.

+HEALTHCHECK_CELERY_RESULT_TIMEOUT = 3  # this is the default time, Adjust the value as needed
+
+# Set the timeout for the expiration of the Celery task in the queue (in seconds)
+HEALTHCHECK_CELERY_QUEUE_TIMEOUT = 3 #this is the default time, Adjust the value as needed
+
+#..... other celery settings.....
