25 -== Troubble shooting / Restarting the camera server ==
28 +there are several cameras that are watched if they have the correct rep rate and if not the server is restarted every 15 min. here is the list of these cameras [[https:~~/~~/ttfinfo.desy.de/FLASHWiki/Wiki.jsp?page=FlashCamerasToWatch~[~[image:url:http://hasfweb.desy.de/pub/TWiki/TWikiDocGraphics/external-link.gif~|~|width="13" height="12"~]~]>>url:https://ttfinfo.desy.de/FLASHWiki/Wiki.jsp?page=FlashCamerasToWatch||shape="rect"]]

27 -If there are problems occurring with the camera ( no image is shown, no update, camera server crashes ...) then it is** mainly 2 reasons:**
28 -
29 -* **There is no trigger connected to the camera → check with trying to run the camera untriggered ...**
30 -* **the server has problems -> restart the server.**
31 -
32 -Even if it seems unrelated ( camera saved only 0 in the DAQ, reprate can not be changed... ) it turned out that restarting the camera server is helpful.
33 -
34 -1. Best to make a screenshot (in expert mode) to the logbook before restarting in case parameter settings are lost ...
35 -1. goto WDserver and press restart. The camera panel will go red and will come back after about 20 seconds ...

41 -If the restart (several times ...) does not help there is an option to make a "deeper restart". This option uses a restart script which includes powercycling of the camera ( for ethernet cameras)and reloading a standard configuration.  One has to be logged in at a linux computer in order to run the script.

51 -== Monitoring system ==
52 -
53 -we implemented a monitoring system for the important beamline cameras in FLASH1 and FLASH2.
54 -
55 -the camera check overview shows a red indicator if the camera is off OR the actual values are different from the saved reference values. Clicking on the red symbol in the camera check one can get to the overview of the parameters. Here a red dot indicates which parameter is different from the reference setting. e.g. if ROI settings have been changed also the reference settings have to be changed accordingly if they are now the new reference !!

57 -The warning is also shown inn the according control panels for the cameras.
