Faster browsing !
A relatively unknown feature in INM is the ability to adjust compression level of data sent to the browser, per operator. The setting is found in the operator property page and works by setting the threshold level for compression. A setting of zero tells INM not to compress data at all for this operator while a setting of 10 tells INM to compress data equal or larger than 10 KB.
Compression setting in operator property page
The feature is recommended to use in almost all scenarios, the downside is that it adds a bit of processing to each request.
Upgraded SNMP Trap monitor
In the next patch of Intellipool Network Monitor several improvements related to SNMP support will be released.
- Upgraded SNMP Trap monitor. The new monitor includes advanced filtering options to trigger on specific variable bindings.
- Built in SNMP trap service that includes filtering on community names and accepted IP numbers/ranges.
- The MIB browser now merges all compiled MIBs during startup and is now super fast when browsing.

Intellipool Lua IDE v3
A new version of Intellipool Lua IDE is in development and will be released later this month. The new version contains many new features that will make life easier for both novice and experienced Lua programmers.
- Debugger with break points and runtime variable watch
- Variable view
- SFTP (Secure File Transfer) client class
- Better performance when editing large Lua scripts
Intellipool Lua IDE v3
About the Intellipool Lua IDE
Intellipool Network Monitor uses Lua as a scripting language to create new types of tests and actions.The Intellipool Lua IDE is provided for free to all INM customers, and is accompanied by several useful libraries:
- FTP
- SSH
- XML
- File handling
- DNS
- WMI
- Windows Performance Counters
- SNMP
- Database (Oracle, SQL server, MySQL)
More information about the class library can be found in the in the documentation.
Linux log file monitoring
The following script works like the Log file monitor, but without the need of having a SMB drive accessible. The script connects to a Unix/Linux device and runs a script searching for a predefined string. Each new test starts where the last test ended (if any new text have been added since the last test).
Monitor Exchange 2010
We have released a number of templates that makes it easier to configure monitoring of Microsoft Exchange 2010. The templates are published in our template forum and will be included into the next patch of Intellipool Network Monitor.
INM v4 Build 5618 released
- New feature: Assign multiple objects to gateway command added.
- New feature: SSL support for notfication mail.
- New feature: Cisco IOS system type with support for CPU, Memory and Process monitoring on various Cisco IOS devices.
- Improvement: Network discovery improved and added to the setup wizard.
- Improvement: MailQOS monitor now has SSL support for incoming and outgoing mail.
- Bug fix: MySQL monitor now remembers the ‘Fail if no rows returned’ setting.
MIB Compiler updated
A new version of the Intellipool MIB compiler have been released and is available on our download page. This new version contains a bug fix for the NOTIFICATION-TYPE macro, a couple of performance improvements and support for MIB files larger than 10 MB.
Data mining with Intellipool Network Monitor
Toplists in Intellipool Network Monitor is updated in real time and contains a wealth of information that can answer many questions, for example
- Which Windows server have the fastest increase in disk utilization the past day, week or month ?
- Which switch have the biggest change in network traffic the latest month ?
- Which web server have the slowest response time ?
Lets take a look at a real world example
Toplist CPU utilization
Here we compare the CPU utilization period average of two different weeks. The list is sorted on monitors with the highest CPU utilization first.
Lets change this list to display the monitors with the biggest change:
Toplist CPU utilization, top movers
This list now shows the entries that changed most between the two weeks, in descending order. As we can see, the object “Build” have a +4.29 % change and thus tops the list. Movers includes both negative and positive changes to previous compared period. Top climbers and top fallers sorts entries based on increese and decreasing values.
Toplist CPU utilization, top climbers
Here we see that the object build still tops the list since it have had the highest increase in average CPU utilization compared to previous week. Selecting top fallers will turn this list around as shown in the image below.
Toplist CPU utilization, top fallers
So why is this important, what problem do it solve ?
With toplists its very easy to spot trouble on the horizon and not when it actually stands next to you tapping you on the shoulder. For example you could show that a certain machine will run out of disk in X number of days or that network consumption have risen 20% compared to last month.
When I say that toplists are calculated in real time, I mean it. Take a close look at the object “Build” and its “Windows performance” monitor, it changes from 4.29 % to 4.28% between the time it takes me to snap the images. INM is capable of doing this, for tens of thousands of data channels without breaking a sweat.
The following metrics are collected and summarized into toplists:
- Bandwidth usage
- Bandwidth utilization
- CPU utilization
- Disk utilization
- Fan speed
- Free disk space
- Free memory
- Humidity
- Memory utilization
- Ping packet loss
- Ping round trip time
- Swap utilization
- Temperature
- Network transfer speed
- Web site fetch time
In addition to this, toplists can be integrated in reports and embedded on the dashboard.
Directory and file monitoring
The directory property monitor is a flexible monitor that can test file count, directory size, relative size changes and age of files in a directory. The test can be limited in scope to files matched by a wildcard.
Directory and file monitoring
The following scenarios can be monitored:
- Directory contains a minimum number of files
- Directory contains a maximum number of files
- Oldest file in directory is not older then a certain number of hours
- Newest file in directory is not older than a certain number of hours
- Relative directory size between test
- The absolute size of files in directory
