Quarter 3 in 2015, Version 15.3.17.2995/2996 to Version 15.3.19.4027/4028

FeaturesSensorsImprovements

  • New [WebGUI]
    • New installations of PRTG will automatically show an initial device tree with devices and sensors in the network. PRTG starts creating it already during the install process of the PRTG server. This happens super-fast so you can see monitoring data at the first start without filling out any forms or going through any detailed setup steps!
  • New [Sensors]
    • The Common SaaS BETA sensor monitors the response times of several common Software as a Service providers like Google Apps, Office 365, Salesforce, and GitHub.
    • This version also includes 4 new sensor types to monitor the cloud services DropboxMicrosoft OneDriveGoogle Analytics, and Google Drive.
    • We replaced the Amazon CloudWatch sensor. You can now choose between 7 CloudWatch BETA sensors, each one dedicated to one CloudWatch service: EBSEC2ElastiCacheELBRDSSNS, and SQS.
    • The new Python Script Advanced sensor can execute a Python script that returns valid JSON or XML and show values in different channels.
    • The SSL Certificate BETA sensor monitors the certificate of a secure SSL/TLS connection.
    • The VMware Datastore (SOAP) sensor monitors the disk usage of a VMware data store. The VMware (SOAP) sensors now also support session pooling.
    • The SNMP Custom Advanced BETA sensor can monitor numerical values from up to 10 custom OIDs in different channels.
    • The SNMP Custom Table BETA sensor can monitor numerical values from an OID that returns an SNMP table.
    • The Oracle Tablespace BETA sensor can monitor a tablespace on an Oracle server. It shows the online status, the overall status, as well as free space and blocks.
    • The Exchange Database DAG (Powershell) sensor can monitor the DAG status of a database on an Exchange server via PowerShell and shows the status of the cluster and replications.
    • The SNMP HP BladeSystem Server Blade sensor and the SNMP HP BladeSystem System Health sensor monitor status and system health of HP BladeSystems via SNMP.
  • Improved [Sensors]:
    • Oracle SQL v2 and Oracle Tablespace sensors support the service name in addition to the SID to identify the target instance.
    • The VMware Host Hardware Status (SOAP) sensor can now ignore known warnings and errors from the VMware host.
    • Windows Network Card sensor can recognize more network cards.
    • WMI Terminal Services (Windows 2008+) supports higher operating systems than Windows 2008
  • Changed [WebGUI]
    • We replaced the Configuration Guru from PRTG with a new setup assistant. This Smart Setup is less complex than the "old" guru and helps creating an initial monitoring setup that already shows interesting data about a network.
    • New installations do not have an automatic object numbering anymore. If you add new sensors, reports, maps, or libraries, the object name will not get a number appended. For details, see this article
  • Improved [Notifications]
    • You can now specify the encoding for syslog messages. Choose between UTF-8 or ANSI for this notification type.
  • Stability and performance improvements for lookups.
  • Improved [Libraries] 
    • The libraries overview now shows the security context for each library, which is the user account that created the library.
    • Performance improvements for libraries.
  • Changed [Security]
    • If the port that is originally configured for the PRTG webserver is not available when using a secure SSL connection, the server now tries port 8443 as fallback to keep the secure connection. If this port is also not available, PRTG tries from port 32000 on until it finds an available port and keeps the SSL connection.
  • Changed [Maps]
    • We replaced existing default icons (PNGs) with SVGs for a better scaling. This changes also the icons in already existing maps. Note that this might affect the look of your existing maps, so please check them after the update.
  • Updated language files

Quarter 2 in 2015, Version 15.2.16.2229/2230 to Version 15.2.17.2803/2804

FeaturesSensorsImprovements
  • New [Remote Probes/Cluster]: PRTG now includes Cluster support for Remote Probes! If you run a PRTG cluster, all your remote probes can now send their monitoring data to all your cluster nodes. For more details, please see our blog article Cluster Support for Remote Probes: Failover Nodes Show Remote Probe Data
  • New [WebGUI] You can set up sensors to run at a specific time on a day. Using a special syntax, you can define the desired point(s) in time in the "Scanning Interval" settings of the PRTG System Administration. For details, please see the Knowledge Base
  • New [Freeware] 
    There are no restrictions for scanning intervals anymore in the PRTG freeware edition. Like in commercial and trial versions of PRTG, you can now use scanning intervals below 60 seconds (we recommend that you do not use less than 10 second intervals).
  • New/Improved [EC]
    • We made the Enterprise Console more compatible to PRTG servers that differ in version: It can now connect to every server where the third number in the version number is equal to the third number of the EC version. For example, EC version 15.1.16.2023 can now connect to any server with the version 15.1.16.xxxx
    • Enhanced filter options for log tables
  • The HTTP Data Advanced BETA sensor can access a web server and retrieve data in XML or JSON encoded format.
  • The SNMP Juniper NS System Health BETA sensor can monitor the system health of a Juniper (netScreen) device.
  • Improved/Changed [Sensors]:

    • All sensors that use the .NET framework now need .NET 4.0. This affects these sensor types: FTP Server File Count Sensor, IP on DNS Blacklist Sensor, Pingdom Sensor, PING Jitter Sensor, Traceroute Hop Count Sensor, Windows Logged In Users Sensor, Windows MSMQ Queue Length Sensor
    • You can now create SSH VMware ESX(i) Disk sensors on vSphere 6.0 (ESXi 6.0)!
    • WMI Custom sensor supports the expression SELECT COUNT(*). You can use this statement if you want the number of entries in the result set to be returned alternatively to a direct value from a field. For example: SELECT COUNT(*) FROM Win32_Process WHERE Name='explorer.exe'
    • EXE/Script Advanced sensor: If the <error>-tag in the custom script contains 0 (<error>0</error>), the sensor does not show an error anymore (Before the value was ignored and the existance of the <error> tag itself triggered an error). Note: All other content with the tag still causes an error, including <error/> and <error></error>
    • When channel limits are reached, sensors now show the "last message" in addition to the threshold sensor message.
    • DHCP sensor now uses "Option: (54) DHCP Server Identifier" as server address, if available
    • Dell MDi Physical Disk sensor supports additional Dell MDi devices; stability improvements

    • We added a globe to all cloud sensors to indicate the sensor status in a nice way.
    • Stability improvements for flow sensors that use a buggy customflowrules.osr
    • SNMP Custom String sensor now always uses its own settings to interpret a value retrieved via Regular Expressions instead of the "Windows Format" settings.
    • PerfCounter IIS Application Pool sensor shows the pool status "unavailable" now as an error. We removed the "beta" status for this sensor.
    • EXE/Script Advanced sensors now keep all white spaces in channel names which are defined in the returned XML code. Previously this sensor type reduced the number of white spaces in channel names automatically to one. This new behavior might result in new channels for your existing EXE/Script Advanced sensors while older channels do not get data anymore.
    • Proxy support for Cloud Ping and Cloud HTTP sensors: These sensor types can use the proxy server as defined in the "Core & Probes" settings of PRTG.
    • Update of the SSH library to support additional key exchange mechanisms (diffie-hellman-group14-sha1).

  • Improved [Security]:
    • We have massively upgraded the encryption security of PRTG's webserver to make the usage of PRTG even more secure.
    • We have upgraded the OpenSSL libraries to version 1.0.1h (these are used for SSL connections of the web server, the core/probe and probe/probe connections as well as for most sensor types that offer SSL).
    • We have locked down the accepted ciphers for SSL connections to the most secure ones that will allow for "Perfect Forward Secrecy" and TLS 1.2, ensuring that a session key derived from a set of long-term keys cannot be compromised if one of the long-term keys is compromised in the future. Even if somebody wire taps your communication with your PRTG server and gets access to your private keys later, he will not be able to decrypt the old data. 
    • Fix for POODLE: We have implemented a fix for this SSLv3 security vulnerability and disabled the outdated SSL 3.0 encryption for PRTG. See this article for details.
    • The admin can set a time after which the WebUI automatically performs a logout to prevent unauthorized access (under System Administration | User Interface).

    • We implemented further improvements to the overall security of PRTG for a better protection against potential attacks.
    • Account pages and QR codes do not include the password hash anymore. 
    • PRTG removes masked passwords that you entered into settings pages from the support bundle and does not send them.
  • Improved [Templates]: You can now exclude specific sensors from a device when you create a device template.
  • Improved [Libraries]: Libraries include now "Add Library Node" and "Add Group" buttons similar to the "Add Device" and "Add Group" buttons in the device tree for easier creation of a library.
  • Improved [Notifications]: New placeholders for syslog receiver and trap receiver notifications show the last 20 entries without any filter before the notification was triggered: %syslogmessages, %trapmessages
  • New [EC]: The Enterprise Console now includes a history for Libraries, Maps, and Reports
  • Improved [WebGUI/Server]:
    • Map editor with better performance and new map objects "QR codes" and "traffic lights"
    • PRTG notifies you if Similar Sensors analysis is off
    • You can filter device lists by tag
    • You can use the logical operators + (must have) and - (must not have) in library and table tag filters.
    • Added a quick print button for QR codes on device lists
    • Tables have more columns to show more information
    • The "Compare Sensors" feature has more options to analyze compared data
    • There is a new visual representation for sensors using lookups with bitfields.

    • SNMP NetApp Logical Unit sensor now with optional alignment monitoring (an additional channel will be added by demand when creating the sensor)
    • HTTP Push Data sensor now shows an expressive error message if the port could not be opened
  • Improved [Security]:
    • OpenSSL libraries have been upgraded from 0.9.8.* to Version 1.0.1h.
    • We include a new PRTG default certificate (with RSA 2048bits) which automatically overwrites the old default certificate (if you use a custom certificate, it will not be touched)
    • When using administrative pages in the webGUI, PRTG now requires that the last credential based login was less than 15 minutes ago. If more time since the last login has passed the user must re-authenticate before he can continue. This secures the webGUI against potential fishing attacks.
    • Browser form auto-complete for login name and password on the login page can now be disabled via a registry key option as security enhancement.
    • Registry key option to deny loading of PRTG web pages in frame elements (use with Caution: denies also loading of maps!). This helps protect against potential clickjacking attacks.

FeaturesSensorsImprovements
  • WebGUI:
    • The "Add sensor" dialog now automatically shows the most used sensor types first (this is calculated for each user)
    • Several webserver and IP settings can now be changed in the "System & Website" settings (was in the PRTG Server Administrator tool before only)
    • The sensors page can now be filtered for objects and tags with an inline filter directly above the table
    • Added a filter option on similar sensors overview page
    • Extended filter for search in tickets
    • Toplists now show range lookups
    • Added a hidden feature that allows showing geo tracking information provided by an Android probe on a geo map (instead of longitude and latitude in tables only). For details, please see our knowledge base article
    • Completely revised and updated look&feel of the Ajax Web GUI
  • PRTG now includes its own ticket system. With the ticket system you can manage and maintain various issues which may appear while monitoring your network with PRTG. Note: The new ticket system replaces the existing 'ToDos' functionality. When PRTG needs to tell the admin something important, it will now create a new 'ToDo Ticket'; a notification about this will now be sent to all PRTG System Administrators user groups.
  • -> Important Change: New ToDo tickets are now assigned to the "PRTG System Administrator" user and notifications for these tickets are sent to this user only. This corresponds to the behavior of the former "ToDos". Right after the introduction of the ticket system, new ToDo tickets were assigned (and notified) to the entire "PRTG Administrators" user group. We reverted this due to user feedback.
