# Installing the exporter
2+
You will use the [Prometheus Memcached Metrics Exporter](https://github.com/prometheus/memcached_exporter).
3+
4+
The `memcached-exporter-deploy.yaml` file provides a deployment with the exporter.
5+
6+
To deploy it, download the file and run:
7+
```
8+
kubectl apply -f memcached-exporter-deploy.yaml
9+
```
10+
> Make sure to edit the argumment `memcached.address` with the proper address name of your memcached instance
11+
12+
# Sysdig Agent configuration
13+
> Requires Sysdig Agent >= v11.3
14+
15+
In the Redis exporter Deployment use the Sysdig annotations to configure the port of the exporter as the scraping port. See the example given in the `memcached-exporter-deploy.yaml` file.
16+
17+
Additionally, you can use the labels to add the namespace, workload type, and name of the database the exporter will take data from.
18+
This way, you can view the metrics associated directly with the database pods and the exporter in Sysdig Monitor.
19+
20+
```yaml
21+
spec:
22+
template:
23+
metadata:
24+
annotations:
25+
promcat.sysdig.com/integration_type: memcached
26+
promcat.sysdig.com/port: "9150"
27+
# Add here the namespace, workload type (deployment, statefulset, replicaset, daemonset)
28+
# and workload name of the Memcached instance that the exporter will take data from
29+
promcat.sysdig.com/target_ns: default
30+
promcat.sysdig.com/target_workload_type: deployment
31+
promcat.sysdig.com/target_workload_name: memcached
32+
```
33+
34+
After configuring the Sysdig annotations, download the sample configuration file and apply it by:
35+
```bash
36+
kubectl apply -f sysdig-agent-config.yaml
37+
```

# Metrics
8+
Memcached generates different topics:
9+
10+
11+
# Number of time series generated
12+
Memcached generates around 100 metrics for each Memcached instance.
13+
