This page shows all of the crawls that are being reported to this server by your grab-site processes.
</p>
<p>
To pause scrolling, move your mouse inside a log window.
</p>
<p>
To show just one crawl, click anywhere on its stats line.
</p>
<p>
To clear all finished crawls, reload the page.
</p>
<p>
Keyboard shortcuts:
</p>
<ul>
<li><kbd>j</kbd> - show next crawl window
<li><kbd>k</kbd> - show previous crawl window
<li><kbd>a</kbd> - show all crawl windows
<li><kbd>n</kbd> - hide all crawl windows
<li><kbd>f</kbd> - move focus to filter box
<li><kbd>v</kbd> - open the start URL of the first-shown crawl window
<li><kbd>?</kbd> - show/hide help text
</ul>
<p>
The color coding for the crawl stats line is:
in progress,
<span class="job-info-done">finished normally</span>,
<span class="job-info-aborted">finished with abort</span>,
<span class="job-info-fatal">finished with fatal exception</span>.
</p>
<p>
Mouse over the crawl start date or the response count for additional information.
</p>
<p>
If your adblocker is enabled for this domain, you will see slower performance, and some URLs will not be displayed.
</p>
<p>
A custom context menu is shown when right-clicking URLs in the log windows below. It can be disabled by adding <kbd><span class="url-q-or-amp">?</span>contextMenu=0</kbd> to the dashboard URL. Firefox users: if you see both the normal and custom context menu, make sure <code>dom.event.contextmenu.enabled</code> is set to <code>true</code> in <code>about:config</code>.
</p>
<p>
For easier text selection in the log windows, add <kbd><span class="url-q-or-amp">?</span>moreDom=1</kbd> to the dashboard URL. (This uses ~25% more memory.)
