= Purpose =
The purpose of the [[mhttpd]] Message page is to
display the contents of the MIDAS [[Message System|Messages log file]] in blocks of 100 lines starting with the most recent messages. This log file contains system and user messages generated by applications connected to the experiment. See [[Message System]] for details.
 
 
= Access the Message page =
The Message Page is accessed from the [[Status Page]] (or one of the other Pages) by clicking on the menu-button
<span style="color: #444444; background-color: #CCCCCC; font-style:italic; font-size: 90; padding:0.25em;
padding-left: 0.5em;padding-right: 0.5em;border:1px solid #808080;border-radius: 5px;margin-bottom:1px;">Messages</span> .
 
;Note
:If "Messages" button is not present on the Status Page, it may have been [[Status Page#page-switch-buttons|suppressed]].
 
= Example =
[[File:message_page.png|500px|left|Figure 1 Example of Messages page for an experiment, Click to enlarge]]
An example of the Message page is shown in Figure 1.
 
Error messages (i.e. those of [[Message System#Message Types|Message Type]] MERROR) are shown in red. The other messages shown are information messages of [[Message System#Message Types|Message Type]] MINFO. 
 
<div style="clear:both">&nbsp;</div>
= Filtering and searching for messages =
 
[[File:message_page_filters.png|500px|left|Figure 2 Filters available, Click to enlarge]]
As of December 2024, MIDAS messages can be filtered using multiple queries. There are 5 filters available, and you can apply multiple filters simultaneously if desired.
 
After typing the filters, one needs to '''press enter or press the 'filter' button''' to start the filtering process. If the filtering takes a long time, the process can be interrupting by clicking the mouse anywhere in the webpage.
 
Messages that match the filters will then appear at the top of the message list, highlighted in green. All the non-matching messages then follow with the regular background colours.
 
<div style="clear:both">&nbsp;</div>
The different filters are:<br>
<span style="color:#eb463d; font-weight:bold;">Program Name</span>: Filter messages based on the name of the program (e.g. Sequencer, mhttpd)<br>
<span style="color:#4295ae; font-weight:bold;">Status</span>: Show only info/error messages etc<br>
<span style="color:#56bb6c; font-weight:bold;">Time</span>: Find messages at a specific timestamp. It searches from the start of the timestamp associated with the message, so "09:45" will find all messages at 9:45am, "9:45" will not match anything (as the timestamps start with 09), and "09:45:56.237" will match only messages at that specific timestamp. Only the time portion can be searched, not the date.<br>
<span style="color:#f3be69; font-weight:bold;">Search Text</span>: Search the actual message content<br>
<span style="color:#98bdf9; font-weight:bold;">Hour</span>: Show only the last x hours/days<br>
