Agent-Cloud link (ACLK)
The Agent-Cloud link (ACLK) is the mechanism responsible for securely connecting a Netdata Agent to your web browser
through Netdata Cloud. The ACLK establishes an outgoing secure WebSocket (WSS) connection to Netdata Cloud on port
443
. The ACLK is encrypted, safe, and is only established if you connect your node.
The Cloud App lives at app.netdata.cloud which currently resolves to 35.196.244.138. However, this IP or range of IPs can change without notice. Watch this page for updates.
For a guide to connecting a node using the ACLK, plus additional troubleshooting and reference information, read our get started with Cloud guide or the full connect to Cloud documentation.
Data privacy
Data privacy is very important to us. We firmly believe that your data belongs to you. This is why we don't store any metric data in Netdata Cloud.
All the data that you see in the web browser when using Netdata Cloud, is actually streamed directly from the Netdata Agent to the Netdata Cloud dashboard. The data passes through our systems, but it isn't stored.
However, to be able to offer the stunning visualizations and advanced functionality of Netdata Cloud, it does store a limited number of metadata.
Read more about Data privacy in the Netdata Cloud in the documentation.
Enable and configure the ACLK
The ACLK is enabled by default, with its settings automatically configured and stored in the Agent's memory. No file is
created at /var/lib/netdata/cloud.d/cloud.conf
until you either connect a node or create it yourself. The default
configuration uses two settings:
[global]
enabled = yes
cloud base url = https://app.netdata.cloud
If your Agent needs to use a proxy to access the internet, you must set up a proxy for connecting to cloud.
You can configure following keys in the netdata.conf
section [cloud]
:
[cloud]
statistics = yes
query thread count = 2
statistics
enables/disables ACLK related statistics and their charts. You can disable this to save some space in the database and slightly reduce memory usage of Netdata Agent.query thread count
specifies the number of threads to process cloud queries. Increasing this setting is useful for nodes with many children (streaming), which can expect to handle more queries (and/or more complicated queries).
Disable the ACLK
You have two options if you prefer to disable the ACLK and not use Netdata Cloud.
Disable at installation
You can pass the --disable-cloud
parameter to the Agent installation when using a kickstart script
(kickstart.sh, or a manual installation from
Git.
When you pass this parameter, the installer does not download or compile any extra libraries. Once running, the Agent kills the thread responsible for the ACLK and connecting behavior, and behaves as though the ACLK, and thus Netdata Cloud, does not exist.
Disable at runtime
You can change a runtime setting in your cloud.conf
file to disable the ACLK. This setting only stops the Agent from
attempting any connection via the ACLK, but does not prevent the installer from downloading and compiling the ACLK's
dependencies.
The file typically exists at /var/lib/netdata/cloud.d/cloud.conf
, but can change if you set a prefix during
installation. To disable the ACLK, open that file and change the enabled
setting to no
:
[global]
enabled = no
If the file at /var/lib/netdata/cloud.d/cloud.conf
doesn't exist, you need to create it.
Copy and paste the first two lines from below, which will change your prompt to cat
.
cd /var/lib/netdata/cloud.d
cat > cloud.conf << EOF
Copy and paste in lines 3-6, and after the final EOF
, hit Enter. The final line must contain only EOF
. Hit Enter again to return to your normal prompt with the newly-created file.
To get your normal prompt back, the final line
must contain only EOF
.
[global]
enabled = no
cloud base url = https://app.netdata.cloud
EOF
You also need to change the file's permissions. Use grep "run as user" /etc/netdata/netdata.conf
to figure out which
user your Agent runs as (typically netdata
), and replace netdata:netdata
as shown below if necessary:
sudo chmod 0770 cloud.conf
sudo chown netdata:netdata cloud.conf
Restart your Agent to disable the ACLK.
Re-enable the ACLK
If you first disable the ACLK and any Cloud functionality and then decide you would like to use Cloud, you must either
reinstall Netdata with Cloud enabled or change the runtime setting in your
cloud.conf
file.
If you passed --disable-cloud
to netdata-installer.sh
during installation, you must
reinstall your Agent. Use the same method as before, but pass --require-cloud
to
the installer. When installation finishes you can connect your node.
If you changed the runtime setting in your var/lib/netdata/cloud.d/cloud.conf
file, edit the file again and change
enabled
to yes
:
[global]
enabled = yes
Restart your Agent and connect your node.
