The problem lies in your function mhistory_init_one() in Mudas.js:1965. You can only call "new MhistoryGraph(e)" with an element "e" which is something

Our default configuration of apache httpd logs every request. MIDAS custom web pages can easily make a huge number of RPC calls creating a
huge log file and filling system disk to 100% capacity

Maybe you remember the problems we had with a custom page in Japan loading it from TRIUMF. It took almost one minute since each RPC request took
about 1s round-trip. This got fixed by the modb* scheme where the framework actually collects all ODB variables in a custom page and puts them
into ONE rpc request (making the path an actual array of paths). That reduced the requests from 100 to 1 in the above example. Maybe the same

13 Jun 2016, Konstantin Olchanski, Bug Fix, example ssl certificate removed
|
I removed the example ssl certificate from the midas git repository (ssl_cert.pem). Now every midas
installation must generate their own certificate - because to have any security at all each encryption
private key has to be unique (and it has to be secret).

At Los Alamos, we have 15+1 frontends - the 15 between them read about 2 or 3
TB/hour and reduce it to 1 to 5 GB/hour which is then sent to the mevb on a 17th
computer. The 16th frontend handles deadtime issues and scalers (small data rate).
