I've used custom views to show clients and my Team many different things that NPM monitors, and those folks really appreciate the service. You can be a rock star in their eyes when you give them something that helps them improve how they and their clients understand their systems and their performance.

Here's how to build a custom View that shows current and recent WAN interface utilization between routers connecting six different data centers. Remember, your new View doesn't have to be of just interfaces on the same switch, or on the same router.

You can build this kind of report for as many interfaces as you'd like, from any switch or router or device interface that's monitored by your NPM. This one shows a single WAN interface on six different routers that connect into the same MPLS cloud:

Here's how to do it:

Create the view:

1. From NPM, go to Settings > Manage Views > Add

2. Customize the new view:

Name it intuitively
Select Summary (there are MANY types of views. Read up on them, test some to get a feel for the extreme versatility of NPM)
Click Submit

3. Edit the View.

You can change its name if you want.
I chose not to enable Left Navigation--this will be simple, and won't load a lot of info.
I added a Custom HTML Resource to Column 1, then cloned it three times. Next I moved one instance into Column 2, and then cloned that one twice. I ended up with three Custom HTML Resources in each column.
I set the width to 500 px for each
I set No View Limitation (but you can add one in if you need it)
Click Done or Preview. Preview lets you see it right away, without assigning it to any Menu Bar. Plus, you can edit those custom HTML fields.

4. Here's the sweet spot to make you rock in the eyes of your boss & peers because it gives you the power to make a really useful view:

Open a second browser window to your NPM
Browse to a router node and open it
Open the interface that faces the WAN
Look at the URL bar and note the NetObject= section. Example:

http://your_server_name_here/Orion/Interfaces/InterfaceDetails.aspx?NetObject=I:XXXXX&view=InterfaceDetails
Copy or write or memorize the NetObject number for use in the next step

5. Edit your new View in Preview, or assign it to a Menu Bar and open it

Click Edit in the top left Custom HTML window
Give it an intuitive Title
Fill in the Subtitle if that helps you better identify the interface or feature you're displaying
Copy and paste this into the html window:

Where I've put in the X's, remove them and enter in the NetObject ID number you wrote down from the previous step
Click Submit

The new page should open, but this time the top left window won't say Custom HTML, it'll show the bandwidth used by that router's WAN interface for the last 10 days:

Now repeat this for every Custom HTML entry you've made, but change the NodeID info to the Node ID that's shown in the Interface Details page URL for new/different WAN routers and interfaces.

OK, you've made a new View. But your team can't access it easily until you assign your new View to the Menu Bar they use. If you don't know how to do that . . .

Here's how to define a new View to add to a Menu Bar:

Go to NPM > Settings > Customize Menu Bars
Edit the Menu Bar you or your team will use to access your new View
Find your new View in the Available Items column on the left
Drag it to the right column, drop it in where you want it.

If you can't find your new View, you'll need to discover its URL. Follow this process:

Open a second browser window and Edit the View by clicking the Preview open
Copy the URL for the new View when you're previewing it
Go back to the original browser window from step 3 and click Add
Type in the Name of your View, paste in the URL address, give it a good Description
I clicked the option to Open in a New Window. It's your choice.
Click OK

Now go back to NPM's Home Page, find the new View in the Menu Bar, and click on it.

Voila!

Tweaking and tuning:

If you're not afraid of a little keyboard editing of html, you can easily change the 10 days to show the last 7 days or last 23 hours or last 17 minutes or last pretty-much-anything. Here's how:

Look for "SampleSize" and "Period" in the code you copied & pasted

Note the SampleSize is 1H, or One Hour.

Node the Period is the Last 10 Days

Edit each window in your view and change the SampleSize and Period to whatever works best for you. Keep in mind that some combinations of SampleSize and Period don't go well together (e.g.: SampleSize=1M and Period=Last 10 Months) because NPM needs to have you be reasonable. If you want a graph showing changes every 1 minute, you have to be polling & collecting the data pretty frequently. Pick a Period that's reasonable for seeing good granularity of 1 minute points, like Last 20 Minutes. If you just see points instead of a line in the chart, you've picked a combination of sample size & period that's too granular for what your NPM has polled. Adjust until you've got something that meets your needs.

Remember to keep the spacing in the html code exactly the same as the example I show above. If you add a space between words, or remove one, you risk breaking the pretty graph output.

Some examples:

Show the Last 3 Hours, in 10-minute increments uses this code:

Note how the graph automatically changed "Last 10 Days" to "Last 3 Hours" in the title. Sweet!

Suppose you like the 10 minute samples, but want to show the last 24 hours. Just change "Last 10 Hours" to "Last 24 Hours":

If it looks great, fire off an e-mail to your Team or your Boss and show off the new functionality you've provided to the organization.

If it doesn't look great, spend a little time fixing it up. Look for typos, fix spelling & punctuation--this is your baby, and folks will judge you by your work.

Swift Packets!

///////////////////////////////////////////////////////////////

Adding Few more explanation here for Cisco Call Manager Showing 99% Memory Utilization in Orion .( just in case someone having this issue )

The reason you are seeing 99% is due to the Cisco MCS returning back those values.

Why its doing this, you have to Open Cisco TAC.

NPM is returning back the values its being supplied with, in this case showing 99%.

Poller type: Used .

N.Memory.SNMP.CpqHostPhysicalMemory =

Memory poller for OpenVMS systems which support proprietary CPQ-Host MIB

Poller utilizes GetSubtree request with two OIDs to gather total and used memory:

cpqHoPhysicalMemorySize = 1.3.6.1.4.1.232.11.2.13.1.

cpqHoPhysicalMemoryFree = 1.3.6.1.4.1.232.11.2.13.2.

Total memory is computed using this formula:

memoryTotal = cpqHoPhysicalMemorySize * 1024

Used memory is computed using this formula:

memoryUsed = memoryTotal - (cpqHoPhysicalMemoryFree * 1024)

MIB Walk shows:

.1.3.6.1.4.1.232.11.2.13.1.0 = INTEGER: 3990 = cpqHoPhysicalMemorySize

.1.3.6.1.4.1.232.11.2.13.2.0 = INTEGER: 60 = cpqHoPhysicalMemoryFree

memoryTotal = 3990 * 1024 = 4085760

memoryUsed = 4085760 - (60 * 1024) = 4085760 – 61440 = 4024320

PercentUsed = 4024320/4085760 = 98.496% = 99%

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

For Linux Server for Poller assigned N.Memory.SNMP.NetSnmpReal

If poller assigned

N.Memory.SNMP.NetSnmpReal

/// memTotalReal = 1.3.6.1.4.1.2021.4.5.
/// memAvailReal = 1.3.6.1.4.1.2021.4.6.
/// memCached = 1.3.6.1.4.1.2021.4.15.
/// memBuffer = 1.3.6.1.4.1.2021.4.14.
/// UsedMemory = (totalMem - availMem - cachedMem - bufferMem) * 1024

.1.3.6.1.4.1.2021.4.5.0 = INTEGER: 2073620 (Total )

.1.3.6.1.4.1.2021.4.6.0 = INTEGER: 1869968 (Available )

.1.3.6.1.4.1.2021.4.15.0 = INTEGER: 88008 (cachedMemory )

.1.3.6.1.4.1.2021.4.14.0 = INTEGER: 51868 (BufferMemory )

( 2073620– 1869968– 88008– 51868 ) = 63776

63776 * 1024 = 65306624 bytes

********************

Vmware ESX Memory Calculation

Supported Poller

The "Memory" Usage and the "Physical Memory" Utilization are calculated differently by Orion NPM.

Memory:

The Memory is the sum of the memory used by the processes listed in the HOST-RESOURCES-MIB:hrSWRunPerfTable (1.3.6.1.2.1.25.5.1).

The OID used is the hrSWRunPerfMem (1.3.6.1.2.1.25.5.1.1.2).

Physical Memory:

The Physical Memory is calculated based on the values populated in the HOST-RESOURCES-MIB:hrStorageTable (1.3.6.1.2.1.25.2.2.3).

The OIDs used are hrStorageSize (1.3.6.1.2.1.25.2.3.1.5), hrStorageUsed (1.3.6.1.2.1.25.2.3.1.6) and hrStorageAllocationUnits (1.3.6.1.2.1.25.2.3.1.4) .

Database transaction log is full - Recovery ( Simple Mode vs Full Mode )

July 13, 2013, 11:05 am

≫ Next: Cisco Reload Reason Report

≪ Previous: Cisco UCS Config Down loader Tool

Growth is either down to 2 reasons:
1 NO DISK SPACE
2 LDF Autogrowth restriction has been reached

First thing I would do is Change Recovery from FULL to SIMPLE if not done so already

http://knowledgebase.solarwinds.com/kb/questions/1359/Changing+Recovery+Model+of+database+back+to+Simple

Here is Good explanation of Simple VS Full Recovery:

http://msdn.microsoft.com/en-us/library/ms189275.aspx

Transaction Log Size

The transaction log should be sized based on the amount of data modifications made to a database and the frequency of the log backups.
Large data modifications, such as data loads or index rebuilds should be taken into account when calculating a log file size.

In simple recovery model the transaction log should not grow as the interval between checkpoints (which truncate the log) is based on the amount of data modifications made.
If the log does grow, it may be that there are long-running transactions or transactions that have been left open. Either may indicate a problem with the application.

In full or bulk-logged recovery model, if the transaction log grows it may indicate that the frequency of data modifications has increased and as such,
the interval between log backups should be decreased. It may also indicate long running transactions or that the log backup jobs are not running properly.

RESOLUTION STEPS :-

.LDF file grows out of control, How to recover:
1.) Make sure recovery model is set for SIMPLE and NOT FULL

http://knowledgebase.solarwinds.com/kb/questions/1359/Changing+Recovery+Model+of+database+back+to+Simple
2.) Backup the database, this will mark the data in the transaction logs as committed and no longer necessary.
3.) Shrink the database again to reclaim the log space. (PLEASE NOTE YOU MUST HAVE SOME FREE SPACE ON THE DISK IN ORDER TO RUN THE SHRINK )

How to: Shrink a Database (SQL Server Management Studio)

How to: Shrink a File (SQL Server Management Studio)

4.) If above doesn’t work as last resort is to detach the database (do not force it to detach if it gives an error that it can not detach, this will damage the database)
once detached delete the .LDF file and reattach the database.
4.) Stop Orion Services.
5.) In the SQL Mgt Studio or Orion Database Manger, right-click on the NetPerfMon database and choose "Detach".
6.) Navigate to that directory where the MDF and the LDF files are stored, and delete ONLY the LDF file.
7.) Go back into the database manager, right-click on your SQL server, and choose "Attach Database."

8.) Select the MDF file, and hit okay.

9) Remove the LDF file entry hit OK

It will recreate will 0KB LDF File automatically.

Future Proof so it doesn’t recoccur
After above all should be fine, but have you check LDF File growth doesnt reoccur.

Also once set to SIMPLE Recovery, LDF file should never really be over 1GB if all running smoothly.
But can also configure LDF to Restricted Growth, so say LDF File on Drive over 100GB Free,

You could restrict LDF to few dozen GB just to be safe,
in case LDF growth reoccurred and LDF goes 100GB and brings down server due lack disk space.

How can i Examine / Open / Analyze what is in Transaction Log file ?

SQL Server transaction log format is not documented and therefore can’t be used to read data from it directly.

There are tools such as ApexSQL Log that can read the transaction log but it’s only because they probably spent a ton of time reverse engineering its format.

ApexSQL Log - SQL Server log explorer | ApexSQL

Options for reading are to:

a) figure the format on your own (not recommended)

b) get yourself a third party tool

c) using functions such as fn_dblog that are also not documented but can give you some details.
