This page helps solve common networking problems with Omniscope.
If you are able to access the internet in your browser, but Omniscope installed on the same desktop cannot (e.g. when using a connector such as a File block to retrieve data over HTTP), it's likely there is a proxy settings issue.
If your computer connects to the internet via a proxy server, often the case in larger corporate environments, Omniscope attempts to detect this automatically. Sometimes this does not work correctly, depending on how the proxy is configured.
Disabling system proxy detection (Windows)
If you are able to browse the internet in your web browser, but Omniscope is unable to connect externally, you may be encountering this problem.
Specifying proxy settings directly
In unusual cases, you may need to configure proxy settings directly. Your proxy settings can be obtained from your network administrator, and typically comprise a proxy server host name and port, for http and https.
On Windows, edit the "installconfig.properties" file following the procedure above, but appending the following options to the "ADDITIONAL_JVM_ARGS" property, space-separated, all on one line, substituting with the necessary host names/IP addresses and prots:
For additional options, such as listing non-proxy hosts, and configuring a SOCKS proxy, see the Java documentation on Networking Properties. All required properties listed there must be appended, space-separated and prefixed "-D", as above.
If using a Windows service, the equivalent arguments e.g. -Dhttp.proxyHost=HHHH -Dhttp.proxyPort=PPPP, must be applied also as multiple additional wrapper.java.additional.n properties in the wrapper.conf file in the service subfolder of the installation folder, e.g.:
On Linux, the same JVM arguments as above, e.g. -Dhttp.proxyHost=HHHH -Dhttp.proxyPort=PPPP) should be applied inside _launch.sh within the installation folder. Append, space-separated, to the JAVA_VM_PARS property before the final quote ('), e.g.:
JAVA_VM_PARS='-Xms64M ... etc. ... -Dhttp.proxyHost=HHHH -Dhttp.proxyPort=PPPP'
