Configure splunkd to use your HTTP Proxy Server

You can set up an HTTP proxy server for splunkd so that all HTTP/S traffic originating from splunkd flows through the proxy server.

To set up a proxy server for splunkd, you can either configure Splunk's proxy variables in server.conf or configure the REST endpoints.

Edit server.conf to configure splunkd to work with your server proxy

[proxyConfig]
http_proxy = <string that identifies the server proxy. When set, splunkd sends all HTTP requests through this proxy server. The default value is unset.> 
https_proxy = <string that identifies the server proxy. When set, splunkd sends all HTTPS requests through the proxy server defined herey. If not set, splunkd uses the proxy defined in http_proxy. The default value is unset.>  
no_proxy = <string that identifies the no proxy rules. When set, splunkd uses the [no_proxy] rules to decide whether the proxy server needs to be bypassed for matching hosts and IP Addresses. Requests going to localhost/loopback address are not proxied. Default is "localhost, 127.0.0.1, ::1">

Use REST endpoints to configure splunkd to work with your server proxy

You can also configure splunkd to work with your HTTP proxy server by modifying the /services/server/httpsettings/proxysettings REST endpoint. To set variables using a REST endpoint, you must have the edit_server capability.

Create the [proxyConfig] stanza:

curl -k /services/server/httpsettings/proxysettings --data name="proxyConfig"

Write to the stanza:

curl -k /services/server/httpsettings/proxysettings/proxyConfig --data "http_proxy=....&https_proxy=...&no_proxy=...."

Read from stanza:

curl -k /services/server/httpsettings/proxysettings/proxyConfig

Delete the stanza:

curl -k -X DELETE /services/server/httpsettings/proxysettings/proxyConfig

For more details and example requests and responses, see server/httpsettings/proxysettings and server/httpsettings/proxysettings/proxyConfig in the REST API Reference.

Configure clusters to work with a proxy

To use the proxy server for communication in an indexer cluster or search head cluster, update the following additional settings in server.conf.

[clustering]
register_replication_address = <IP address, or fully qualified machine/domain name. This is the address on which a slave will be available for accepting replication data. This is useful in the cases where a slave host machine has multiple interfaces and only one of them can be reached by another splunkd instance>
Only valid for mode=slave


[shclustering]
register_replication_address = <IP address, or fully qualified machine/domain name. This is the address on which a member will be available for accepting replication data. This is useful in the cases where a member host machine has multiple interfaces and only one of them can be reached by another splunkd instance.>

Comments

I have been unable to get this working for checking apps in the UI. I set up the proxy variables in server.conf, but still get errors when the Splunk UI needs to go through authenticated proxy. As most companies who care about security use authenticated proxies, it should not require Google searches and calls to support to figure out how to configure them.
