I was trying to get apache to proxy me my oservium and my opsview:
observium.conf
<VirtualHost *:443>
ServerName observium.openfactory.ch
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
SSLEngine on
SSLCertificateFile /etc/ssl/custom/wildcardopenfactory.ch.crt
SSLCertificateKeyFile /etc/ssl/custom/wildcardopenfactory.ch.key
SSLCertificateChainFile /etc/ssl/custom/wildcardopenfactory.ch.chain.crt
ProxyRequests Off
ProxyPass / http://10.2.3.4/
ProxyPassReverse / http://10.2.3.4/
</Location>
</VirtualHost>
opsview.conf
Works absolutely the same.
Important is only this setting for Observium (otherwise CSS won’t work!)
$config['base_url'] = "https://observium.openfactory.ch:443"; which can be set in /opt/observium/config.php
