CF Server Manager Questions

Guide ,
Jan 30, 2011 Jan 30, 2011

Hello

I think CF Server Manager can be a useful tool for anyone working on multiple CF systems. I have some CF Server Manager questions.

When using Server Manager you get 3 views.

1)      Quick

2)      Details

3)      Errors

Quick View:

What are the Alerts and Warnings? How to configure them to get some meaningful information?

Details View:

What are Running Requests and why no details? What are the Errors? What do the Errors relate to eg CFadminUI > Debugging & Logging > Log Files, CF\runtime\logs\OUT or EVENT log?

Error View:

Why no information though details view says errors exist?

Thanks in advance, Carl.

Carl, the server manager is indeed for viewing multiple systems at once. To see the details of running requests (or errors), one instead should view the Server Monitor (which is available as a link in the Server Manager for each listed server). Does that make sense?

(I'll add that the errors tab in the Server Manager is instead about errors in comm. between the Svr Mgr and the instances it's talking to.)

Thanks for that detail Charlie, that make reading the help online somewhat easier to understand. Of course I am trailing Server Manager with CF Standard and that is where the functionality breaks down since this is what happens from the link:

Server Monitoring > Server Monitor > This feature is not available in this edition of the ColdFusion server.

Perhaps I should trial Server Manager  with CF Enterprise / multiserver instances and see how that goes.

Cheers, Carl.

To be clear, no, you cannot use the Server Manager to watch a Standard deployment of CF, only other Enterprise deployments.

Don’t shoot the messenger hey Charlie?

I have to say I find the CF Server Manager needing Enterprise a little disappointing. When I look at the CF9 features from the link URL’s provided seems to me Standard edition has the check box and no caveats listed like some functionality is not present. Or am I missing something?

Sorry Carl, I thought you were referring to the Multiserver Monitor (which has much the same functionality of the Server Manager). The latter is in Standard but the former is not. Also, while the Server Manager does also let you link to the Server Monitor for a listed instance, the Server Monitor (like the MultiServer Monitor) is not available on Standard.

So back to your first question: the Server Manager lets you see things at a high level, but it does not let you see them in detail (what requests are running, for how long, etc.) That is only in the Server Monitor, and only on Enterprise. (Or you can get much the same information using the commercial tools FusionReactor or SeeFusion on Standard.)

One little aside: I confirmed that the Server Manager did work on a CF 9.0 Standard server, and that it still offered a link to the Server Monitor to such an instance (which perhaps it should not, if it's Standard). Oddly, the Server Monitor even opened up, but all its pages were blank. I would have expected, instead, that it wouldn't open at all. (In fact, if you try to open the Server Monitor using the Admin, the Monitor page it displays says that it's not supported, and just doesn't offer links to launch it. So it may be that you can try if you know the URL: /CFIDE/administrator/monitor/launch-monitor.cfm, but as I'm seeing, it just shows up as mostly blank.) To be clear, you don't see the Start buttons (but that often happens even on Enterprise and you can just refresh to get them to show up), but you also see nothing in the Memory Usage Summary page.

Just to clarify - I find CF Server Manager does work on CF Standard in an overview sort of fashion however as Charlie points out the more granular functions do not work requiring Enterprise edition which supports Server Monitor.

I hate to sound like a complainer Adobe however there does  not seem to be any caveats on the CF9 feature list that mentions Server Manager not fully functional in Standard or it indeed uses some of Server Monitor which is only on Enterprise (although I have been known to be wrong before : - ) ).

So where does that leave me. I was thinking CF Server Manager would be a great tool to use however:

-only gives overview of CF Standard

-does not overly assist with applying Cumulative Hot Fixes when CHF have manual steps

-can inspect things like datasources, mappings and JVM details even alter tho I can do that anyway via CFadminUI

Wondering how anyone else finds the CF9 feature Server Manager on CF Standard edition - good / some use / what is Server Manager?

Thanks again, Carl.

I won't speak for Adobe, but I will suggest that in offering the Server Manager (for Standard), they have at least given us a better alternative to the longstanding and more-meager CFSTAT and JRun Metrics. No, they have not given us the full Server Monitor, but that's part of their strategy for regarding that those with such "higher performance" concerns should buy Enterprise.

Not contending against your opinion that they should consider adding more monitoring in Standard. Just asserting that at least the Server Manager is a step in the right direction.

Note also that the Server Manager does still more than high-level monitoring, but also provides an AIR-based interface to Admin functionality, and adds the new ability to compare settings and apply hotfixes across servers, and so on. (For those needing that on CF 8, or more for CF9, there is also the free MerlinManager.com software.)

As for the comparison page, I also don't feel (personally) that there's anything deceitful. It does clearly say that the server manager is on Standard and Enteprise, while the Monitoring is only on Enterprise. As for what those distinctions mean, well, that matrix is terse in many ways (trying to fit as much on a page as they can). I don't see it as being intentionally duplicitous.

As for your "where does that leave me points"

-only gives overview of CF Standard

Yes, but again I'd say that's better than things were prior to 9

-does not overly assist with applying Cumulative Hot Fixes when CHF

have manual steps

Yes, that's true that it doesn't help with manual steps, though it allows you to apply them yourself. Even Merlin doesn't really highlight when manual steps are needed. For those who may want to tell Carl to "just read the technote", I think he's referring to something I've blogged about where when you skip CHFs, you need to make sure that an earlier one didn't have its own manual steps (http://www.carehart.org/blog/client/index.cfm/2010/12/12/cfmyths_cumulative_hotfixes).

-can inspect things like datasources, mappings and JVM details even

alter tho I can do that anyway via CFadminUI

Well, yes, it's true you could do those things yourself via the Admin API. The same could be said of the CF Admin itself: you can do things yourself if you want to. That's why the Admin API was introduced in CF 7. Now, as to what the Server Manager brings to the table, it's that a) it's an AIR app and b) you can do the comparisons among servers (right-click on a server and choose "diff with").

The Server Manager also integrates with the Server Monitor in that if one sets an alert, there's an option there "notify client" which if enabled means that if you have the Server Manager started on your desktop (even if minimized), it will cause your system tray to popup a notification of that alert. Granted, that's another "Enterprise-only" feature, so not a winning point for your case, but still, I'm just asserting why, along with the above, the Server Manager does offer value for all CF9 users.

Could they improve it and add more? Sure, and it's fair to ask--though I don't know that they really watch these forums for such ideas. You'd be better off making your concerns known on the wish form (more at http://www.carehart.org/blog/client/index.cfm/2008/12/13/finding_the_cfwish_form).

All that said, we're still on the same side, Carl. I appreciate your stepping in often to share insights here. I'm not trying to pick a fight here. You asked for what others thought, and I'm just sharing my opinion as one who of course pays a lot attention to all this stuff and wants to help others do so as well.

Charlie’s opinion is always welcome. I am grateful that you take the time to read and many times reply at length. No I do not feel like I am in a contest or taking overly contrary stand.

Do find it a little curious there does not seem to be much of a take up / interest / views / replies on subjects CF Server Manager related. Perhaps it is “to new” or “to AIR” or not well adopted yet or everyone is happy with the tools they have. Is it useful enough in my CF environment - not sure will keep trying.

Cheers, Carl.

Thanks, Carl, and like I said, I do realize we're on the same side. I was just offering a counter to your observation. More important, I was saying that any concerns with the Server Manager functionality (or lack) would be best addressed to that wish form.

As for why there's little uptake/discussion of the Server Manager, I think there are many factors:

- first, it's new, and perhaps few are noticing it

- second, it may not be clear to them how it differs from the older MultiServer Monitor (and on the "Server Montoring" page for Enterprise/Developer users, it shows up 3rd, after Launch Server Monitor and Launche MultiServer Monitor, so they may not even see it.)

- worse, third, on Standard, there isn't any link to it offered on the Admin Server Monitoring page. Instead, it still reports (as it did for 8) that server monitoring is not available on Standard. It seems a bug that it doesn't list a link to launch the server manager (and still an issue on 9.0.1). I've filed a bug report today about that (http://cfbugs.adobe.com/cfbugreport/flexbugui/cfbugtracker/main.html#bugId=86143).

- then too, even if one does launch it on Standard, they may find (as I have) that the "details view" shows "no data" for the columns about requests (running/active/queued). I filed a bug report about that today (http://cfbugs.adobe.com/cfbugreport/flexbugui/cfbugtracker/main.html#bugId=86141)

Folks running Standard may want to visit those links and "vote up" the bugs.

Carl, since you're running on Standard, I'm curious what you're seeing about those.

As you notice Charlie with CF Standard, Details View shows no data for "request" items. Here is a print screen for CF9 Standard on my network (LAN) on an external server customer site (EXTERNAL) and localhost (however my localhost is CF developer ie no Standard licence install).
