История изменений программы Advanced Host Monitor

Изменения в программе Advanced Host Monitor 11.62 (18.10.2018):

• Copy folders: "Adjust Masters" option
• New "Check and copy" function
• Remote Control Console supports Views based on expressions with historical variables like `%STAT60DAYS_DeadRatio%` (e.g. `%STAT60DAYS_DeadRatio%`>5)
• RCC: If you are creating SLA reports for a large amount of tests (e.g. 20,000 tests) on remote system using Remote Control Console, new version will get historical data from HostMonitor and create SLA reports much faster.

• Mail Relay test supports secured and encrypted connections (SSL/TLS) to SMTP servers. You may set "None" option to use unencrypted connection, select "Implicit" or "Explicit" (StartTLS) to use encrypted connection (such options for POP3 and IMAP servers where implemented years ago)

• Stop service
• Start service
• Restart service
  These actions support comma separated lists (or LF separated) and can stop, start or restart many services, one by one. E.g. you may use %Reply% variable for action triggered by Service test that checks ALL "Auto" services.
• HMScript action
  CopyAllTests command supports new optional parameter "-adjustMasters". With this option enabled, if dependant tests copied with master(s) then HostMonitor adjust master-dependant relations for newly created tests. E.g. if you copy 6 tests (5 NetApp tests that depends on 1 Ping test) then new NetApp tests will depend on new Ping test (if you are using folder-related variables for target IP address, then new tests will start to monitor new device without any manual adjustments).

• Telnet command CopyAllTests supports new optional parameter "-adjustMasters", works similar to CopyAllTests HMScript command (see above).

• Generate reports action: "Use reports pool" option could work incorrectly and sometimes did not create reports

Изменения в программе Advanced Host Monitor 11.54 (28.08.2018):

• HMScript: new parameters for SetTestParam, ReplaceTestParam, SetTestParamByID and ReplaceTestParamByID commands:
  - Threshold (also ThreshouldUp can be used)
  - Threshold2 (ThresholdDown can be used)
  Now you may set limits for most of test methods using script, e.g. you may set limit for free memory or free disk space, loss ratio or jitter limits for Ping tests, set limits for CPU load, UPS load or battery temperature and so on.
  Some examples:
  SetTestParam "main router" Threshold "50 %"
  SetTestParam "main router" Threshold2 "50 ms"
  SetTestParam _AllMemory Threshold "20 %"
  SetTestParam _AllTraffic Threshold "55 KB/sec"
  SetTestParam _AllTraffic Threshold "33 pkt/min"
  SetTestParam _AllTraffic Threshold "22 pkt"
  ReplaceTestParam _AllUPSTemp ThresholdUp 65 55
  ReplaceTestParam _AllUPSTemp ThresholdDown 15 10
  ReplaceTestParam _AllFreeSpace Threshold "20 %" "17 %"
  ReplaceTestParam _AllFreeSpace Threshold "5 GB" "8 GB"
  ReplaceTestParam _AllFreeSpace Threshold "6 GB" "15 %"
  SetTestParamByID 11054 Threshold "10 MB"
  
  
• Process test in SNMP mode checked up to 1024 processes, now it checks up to 4096 processes
  
  
• Minor GUI improvements (HostMonitor and RCC)
  

• In some rare cases "report generator" module could make HostMonitor unresponsive for several minutes (sometimes this may happen if you set SLA reports with charts for a large set of tests; also HostMonitor could slow down when many test items launch Generate Reports action with disabled "use reports pool" option and HostMonitor does not have access to the target folder). Fixed
  
  
  

Изменения в программе Advanced Host Monitor 11.51:

• Fixed several problems in Remote Control Console GUI

Изменения в программе Advanced Host Monitor 11.32:

• Apache test (Apache HTTP Server is a free and open source web server for UNIX and Windows platforms).
  HostMonitor can check the following Apache server performance metrics:
  - Connections/sec
  - Bytes/sec
  - Busy workers
  - Idle workers
  
  
• NGINX test (NGINX is high performance HTTP and reverse proxy server).
  HostMonitor can check the following performance metrics:
  - Connections/sec
  - Requests/sec
  - Non handled ratio
  - Non handled count
  - Current connections
  - Busy(active) connections
  - Waiting(idle) connections
  - 1xx responses ratio
  - 3xx responses ratio
  - 4xx responses ratio
  - 5xx responses ratio
  - Total error responses ratio
  - Cache hit ratio
  - SSL fails ratio
  - SSL handshakes / sec
  - Health checks
  
  
• Tomcat test (Tomcat is one of the most commonly used servers for Java applications).
  HostMonitor can check the following performance metrics:
  - Free memory ratio (%)
  - Used memory (MB)
  - Busy threads
  - Busy threads ratio (%)
  - Requests/sec
  - Bytes/sec
  - Processing time
  - Errors/sec
  - Errors/requests ratio
  
  

• HostMonitor (RCC): new popup menu "Switch to folder N" switches from Views pane to Folders pane and selects folder where current test item is located
• HostMonitor (RCC): new option for custom menu items. If command starts with [copy] keyword then HostMonitor does not execute command, instead it resolves variables and copies data into clipboard. E.g. if you set menu item using the following command line [Copy] Test: %TestName% Reply: %Reply% select the test and click on menu, then HostMonitor will copy into clipboard buffer string with test name and reply value.
• New telnet command `TDID ` (or `TestDependentsByID `) shows list of IDs of all test items that depend on Master test specified by TestID

• HostMonitor (RCC): if you copy multi-line text from clipboard into User Defined Variables list (Global variables), GUI did not process such operation correctly. Fixed

Изменения в программе Advanced Host Monitor 11.24:

New feature  New test methods

UPS Health
UPS Load
UPS Charge
UPS Voltage In
UPS Voltage Out
UPS Temperature
UPS Remaining Time
Using SNMP protocol HostMonitor may monitor uninterruptible power supply devices,
 check battery status, retrieve active alarm conditions, monitor battery temperature
 and charge level, input voltage and so on. HostMonitor can check various UPS models
 from APC, CyberPower, Hewlett-Packard Company, Eaton, IBM, TrippLite and more.

Improvements  Network Discovery

Replication option "Adjust test settings automatically" tells HostMonitor to adjust
 some settings according to target host OS and detected protocols. Now it may set 
UPS type when you copy UPS related test
New Replication option "If Master tests not copied, try to find new masters using 
existing tests as examples" can be very useful when you already have set of test 
items related to the target hosts but you want to replicate some new test methods.
 If you copy just dependent items, this option tells HostMonitor to check existing
 test items located in the target folder, find tests with similar "master-pattern"
 and set the same masters for new test items.

Improvements  Actions:

The following group names can be used in HM scripts
_AllUPSHealth   _AllUPSLoad   _AllUPSCharge   _AllUPSVoltageIn   _AllUPSVoltageOut  
 _AllUPSTemp   _AllUPSTimeE.g.  DisableTest   _AllUPSLoad  EnableTest   _AllUPSTemp
  PauseTest   _AllUPSHealth 10

Improvements  Acknowledgments:

Normally HostMonitor resets operators comments when test status changes from "bad"
 to "good". Now you may change this behavior. If you insert KeepAckCommentNDays=3
 line into [Logging] section of hostmon.ini file and restart HostMonitor, it will
 keep comments that are up to 3 days old (you may use different number, e.g. keep
comments for 5 or 15 days)

Изменения в программе Advanced Host Monitor 10.70:

"Import from text file" function improved
Undocumented option for HTTP Request action
allows you to change maximum allowed length of HTTP header
("undocumented" means this option is not accessible thru GUI;
you may add line like HttpActMaxHeaderLen=1024 into [Misc]
section of hostmon.ini file and restart HostMonitor)

Изменения в программе Advanced Host Monitor 10.64:

HostMonitor, RCC, Passive and Active RMA agents for Windows - Folder/File Availability test method supports FTP, FTPS and SFTP protocols.
Now Folder/File Availability test can check:
files on local file system;
files on shared network disk connected to HostMonitor system (using network client installed on local Windows system);
files on system where Remote Monitoring Agent is running;
files on shared network disk connected to the system where Remote Monitoring Agent is running;
files on FTP and FTPS server (FTPS uses SSL);
files on SFTP server (SFTP uses SSH protocol).
 The following issue was resolved
Log Analyzer: in some cases interactive HTML report did not show charts. Fixed

Изменения в программе Advanced Host Monitor 10.20:

• HostMonitor and RMA for Windows support SNMP v3 privacy - DES, 3DES and AES encryption.
• SNMP Get test method: fixed mistake related to "Check OPAQUE data for float numbers" option

• Now you may adjust colors for charts generated for SLA reports. You may create one or several color profiles, assign name starting with "SLA " or "SLA-" (case insensitive, e.g. "Sla Blue palette", "SLA-White") and use these color palettes for SLA reports
• New HostMonitor creates SLA reports with charts 2-4 times faster (depends on system CPU)
• If you setup HostMonitor to generate many reports (especially SLA reports with charts) using timer (e.g. generate 200 reports for 100 folders every 5 min), HostMonitor responsiveness could be very poor. New version works better
• HTML reports optimization ("simple" HTML reports)
• HTML log files optimization

• HTML reports optimization
• New variable can be used in report template: %TestID% - represents unique ID of the test
• If you are not using templates and you need to use links pointing to some specific test items, you may add Reports_AddTag=1 line into [Misc] section of logsman.ini file. Then Log Analyzer will add tags like to each item within reports (using real test ID instead of 55)
• New option for reports "Create charts, interactive mode" allows you to create reports like these sample1, sample2 (click on test item to open/close chart)
