Helm is a tool for managing packages of pre-configured Kubernetes resources using Charts. This integration allows you to collect and ship diagnostic metrics of your .NET application in Kubernetes to Logz.io, using dotnet-monitor and OpenTelemetry. logzio-dotnet-monitor runs as a sidecar in the same pod as the .NET application.
Sending metrics from nodes with taints
If you want to ship metrics from any of the nodes that have a taint, make sure that the taint key values are listed in your in your daemonset/deployment configuration as follows:
tolerations:
- key:
operator:
value:
effect:
To determine if a node uses taints as well as to display the taint keys, run:
kubectl get nodes -o json | jq ".items[]|{name:.metadata.name, taints:.spec.taints}"
Standard configuration
Select the namespace
This integration will be deployed in the namespace you set in values.yaml. The default namespace for this integration is logzio-dotnet-monitor.
To select a different namespace, run:
kubectl create namespace <<NAMESPACE>>
- Replace
<<NAMESPACE>>
with the name of your namespace.
Add logzio-helm
repo
helm repo add logzio-helm https://logzio.github.io/logzio-helm
helm repo update
Run the Helm deployment code
helm install -n <<NAMESPACE>> \
--set secrets.logzioURL='<<LISTENER-HOST>>:8053' \
--set secrets.logzioToken='<<PROMETHEUS-METRICS-SHIPPING-TOKEN>>' \
--set-file dotnetAppContainers='<<DOTNET_APP_CONTAINERS_FILE>>' \
logzio-dotnet-monitor logzio-helm/logzio-dotnet-monitor
- Replace
<<NAMESPACE>>
with the namespace you selected for this integration. The default value isdefault
. Replace<<LISTENER-HOST>>
with the host for your region. For example,listener.logz.io
if your account is hosted on AWS US East, orlistener-nl.logz.io
if hosted on Azure West Europe. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071. Replace<<LOG-SHIPPING-TOKEN>>
with the token of the account you want to ship to. - Replace
<<DOTNET_APP_CONTAINERS_FILE>>
with your .NET application containers file. Make sure your main .NET application container has the following volumeMount:
volumeMounts:
- mountPath: /tmp
name: diagnostics
Check Logz.io for your metrics
Give your metrics some time to get from your system to ours, then open Logz.io. You can search for your metrics in Logz.io by searching {job="dotnet-monitor-collector"}
Customizing Helm chart parameters
Configure customization options
You can use the following options to update the Helm chart parameters:
-
Specify parameters using the
--set key=value[,key=value]
argument tohelm install
or--set-file key=value[,key=value]
-
Edit the
values.yaml
-
Overide default values with your own
my_values.yaml
and apply it in thehelm install
command.

Uninstalling the Chart
The Uninstall command is used to remove all the Kubernetes components associated with the chart and to delete the release.
To uninstall the dotnet-monitor-collector
deployment, use the following command:
helm uninstall dotnet-monitor-collector
