openHistorian 2.8.157 Latest
Latest

This is the official release for openHistorian v2.8.157

This is version 2.8.157 of the openHistorian, released on March 21, 2022

FYI - Windows installers for openHistorian v2.8.157 prior to 4/9/2024 were suspectable to CVE-2024-24810. The installer download below has been updated to compensate for this vulnerability. Note that since this only affected the installer, the openHistorian version remains the same. If you have an installer (i.e., the openHistorianSetup.msi file) cached on your system, it is recommended to replace the file from the updated download below.

This is an optional minor point release of openHistorian v2.8, see updates below for details.

NOTE: If you are upgrading from a prior version of the openHistorian, older than v2.8, you must migrate your existing configuration to use the latest database schema when the Configuration Setup Utility is run after the installation completes - this version includes schema updates.

Updates Since 2.8 version released in Nov 2021

  • Added UpdateExistingTagCompressionState parameter to PI Adapter to control if tag compression attribute should be updated on existing tags when UseCompression parameter is enabled
  • Added time reasonability parameters to PI Adapter
  • Added SkipDigitalAlternateTagSync operation with PI Adapter Tag Sync
  • Added Gzip export option to GEP data extractor tool
  • Updated DeviceStats adapter SQL
  • Added configuration timeout parameters to DeviceStats adapter
  • Improved phasor protocol adapter for manual measurement key lookups
  • Updated phasor protocol to better handle auto-repeats with spanned CFG3 frames
  • Fixed phasor protocol CFG3 Guid attribute display
  • Simplified IEEE C37.118 concentrator use of Device model (no local proxy settings required)
  • Fixed encoding issues with ValidateAssemblyBindings
  • Added screens for oscillation reporting that appear when oscillation adapter and reporting table is detected

See latest updates since previous release candidate.

Security Updates:

This version of the openHistorian corrects two vulnerabilities, both related to the web interface in the version 2.7 release of the openHistorian – note that the main branch and nightly builds have been patched since September 2020. The vulnerabilities were (1) CVE-2020-11023, related to the version of the jQuery JavaScript library embedded with openHistorian, and (2) CVE-2019-10768, related to the version of the Angular JavaScript library embedded with openHistorian.

The jQuery JavaScript library is heavily used by the openHistorian web interface, including the login page. The Angular JavaScript library is only used on the “Real-time Measurements” screen and a user must be authenticated to access the screen. Both reported vulnerabilities require vulnerable JavaScript code to be exploited by an attacker and would require an authenticated user execute the modified code.

Note that none of the GPA web-based code actually used any of the affected functions identified in the JavaScript library vulnerabilities, as such, the noted vulnerabilities could only be exploited by manually modifying an existing or creating a new web page in the openHistorian. Updating a web page in openHistorian requires physical file access to the “wwwroot” folder in the openHistorian. Generally, GPA does not consider either of these vulnerabilities as exploitable within an unmodified openHistorian deployment.
FYI, also including the following note on the recently discovered Grafana vulnerability:

Grafana Vulnerability Notice

The version of Grafana distributed with the latest openHistorian is 7.3.4. Deployed standalone versions of Grafana prior to versions 8.3.2 and 7.5.12 are affected by the following vulnerability: CVE-2021-43813. This is a directory traversal vulnerability for fully lowercase or fully uppercase .md files which is limited in scope and allows access to files with the extension .md to authenticated users only.

Importantly, however, this vulnerability does not affect Grafana instances hosted by the openHistorian. The Grafana instance hosted by the openHistorian runs behind a reverse proxy in the openHistorian web interface. The openHistorian web interface normalizes the PATH requests going to Grafana which mitigates the vulnerability. The only access allowed to the openHistorian hosted Grafana instance is through the openHistorian web interface that requires user authentication.

New Tools / Features:

  • AdapterExplorer Tool - analyzes the configuration of a Time-Series Library system validating inputs, outputs and current values

openHistorian 2.7

Official stable release of version 2.7 of the openHistorian (v2.7.195).

NOTE: If you are upgrading from a prior version of the openHistorian, you must migrate your existing configuration to use the latest database schema when the Configuration Setup Utility is run after the installation completes - this version includes schema updates.

Security Fixes

Security scans of older releases of the openHistorian have identified two JavaScript library vulnerabilities included from the Grid Solutions Framework, specifically jQuery and knockout. Installation of version 2.7 of the openHistorian resolves these reported issues through library updates.

For jQuery the vulnerability was CVE-2019-11358:

jQuery before 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true, {}, ...) because of Object.prototype pollution. If an unsanitized source object contained an enumerable proto property, it could extend the native Object.prototype.

Because of the way GPA uses jQuery within the openHistorian, GPA deems the risk of this vulnerability to be low.

For knockout the vulnerability was WS-2019-0015:

Knockout, before 3.5.0-beta, has an XSS injection point in “attr” name binding for browser IE7 and older.

Exploitation of the knockout vulnerability required the use of IE7. Since the openHistorian requires IE11 or better to function, GPA deems the risk of this vulnerability to be low. However, GPA does suggest updating to a newer, more secure browser regardless.

openHistorian v2.6

Note: This is not the latest version.

Official stable release of version 2.6 of the openHistorian (v2.6.30).

NOTE: if you are upgrading from a prior version of the openHistorian, you must migrate your existing configuration to use the latest database schema when the Configuration Setup Utility is run after the installation completes - this version includes schema updates.

New Synchrophasor Input Wizard with Automated Device Calculations

This new version of the openHistorian includes a new web-based synchrophasor device wizard that provides the ability to create custom calculations from a template:
image
User defined calculations can be added to a .TagTemplate file and be applied to new or existing devices and can be reapplied if the template is updated. See included Full Checkout Calculations for an example.

New Cloud Data Push Adapter

As a new feature, this release includes an adapter (the first of many) to enable the openHistorian to push JSON-formatted data directly to the cloud. This first adapter, called AzureEventHubOutputAdapter, will push streaming time-series data (like synchrophasor data) to an Azure Event Hub.

Updated Grafana with Included SCADAvis Synoptic Panel

Also updated in version 2.6 of the openHistorian is the included instance of Grafana, now at version 6.2.5. The frequently used piechart and clock plugin panels are now automatically included as part of the openHistorian install. Additionally, the SCADAvis Synoptic Panel has been included to allow animated advanced Scalable Vector Graphics (svg) screens to be created in Grafana -- such as seen in the example below:
image
To create new screens for this panel, see the HTML5 Synoptic Toolkit. This tool can create new svg screens that can be integrated into Grafana with data queried from the openHistorian and other sources.

Deployments of the openHistorian with hosted Grafana integration include pre-configured data sources for the primary data and statistics archives named OHDATA and OHSTAT respectively. The latest versions of the openHistorian and OSIsoft-PI Grafana data source are included, as well as a default System Status dashboard.

Enhanced Point Tag Naming Convention

This version of the openHistorian includes an updated default tag naming convention for new measurements. If you are upgrading from a prior version, you can manually update your PointTagNameExpression in the systemSettings sections of the openHistorian.exe.config and openHistorianManager.exe.config files using the included XML Configuration Editor tool.

The new expression is as follows:

[?{CompanyAcronym}!=[{CompanyAcronym}_]]{DeviceAcronym}[?{SignalType.Source}=Phasor[-eval{'{PhasorLabel}'.ToUpper().Replace(' ','_')}[?{BaseKV}>0[_{BaseKV}]][?{SignalType.Suffix}=PA[:ANG]][?{SignalType.Suffix}=PM[:MAG]]]][?{SignalType.Source}!=Phasor[:{SignalType.Acronym}[?{SignalIndex}!=-1[{SignalIndex}]]]]

This new expression will create tag names like the following:

  • TESTDEVICE-500_KV_BUS1:ANG
  • TESTDEVICE-500_KV_BUS1:MAG
  • TESTDEVICE-LAGOON_CREEK:ANG
  • TESTDEVICE-LAGOON_CREEK:MAG
  • TESTDEVICE:FREQ

You can force all tag names to be updated using the new expression by setting the Arguments field of the PhasorDataSourceValidation record of the DataOperation table to renameAllPointTags=true and issuing a ReloadConfig command from the openHistorian console.

Note: PMU Connection Tester is installed separately:
https://github.com/GridProtectionAlliance/PMUConnectionTester/releases

Installation: The following YouTube video walks through the process of installing and configuring the openHistorian and covers the process of building custom displays from openHistorian data using Grafana visualizations.

openHistorian v2.5

Note: This is not the latest version.

Official stable release of version 2.5 of the openHistorian (v2.5.6).

NOTE: if you are upgrading from a prior version of the openHistorian older than 2.4, you must migrate your existing configuration to use the latest database schema when the Configuration Setup Utility is run after the installation completes - this version includes schema updates.

This version of the openHistorian allows Grafana to be seamlessly integrated such that the openHistorian primary web site can act as a reverse proxy to an instance of Grafana accessible from the main web URL, e.g.: http://localhost:8180/grafana/. When configured in this mode, the openHistorian will auto-launch the grafana-server executable and act as a front-end server for Grafana. Additionally, the openHistorian will maintain user security synchronization such that a user with an Administrator role in openHistorian will also have an Admin role in Grafana, or if a user has an Editor role in openHistorian they will have an Editor role in Grafana, and so on.

See the new YouTube video that walks users through the process of installing and configuring the openHistorian and covers the process of building custom displays from openHistorian data using Grafana visualizations.

Deployments of the openHistorian with hosted Grafana integration include pre-configured data sources for the primary data and statistics archives named OHDATA and OHSTAT respectively. The latest versions of the openHistorian and OSIsoft-PI Grafana data source are included, as well as a default System Status dashboard:

Migrating to openHistorian 2.0 in other GPA Products

It is recommended to install a stand-alone instance of the openHistorian 2.0 and subscribe to other data sources, e.g., using GEP, to get data in the openHistorian. However, using the openHistorian.Binaries.zip download that can be found here, you can extract the needed openHistorian 2.0 assemblies needed to upgrade any openHistorian 1.0 instance running in a GPA product built using the GSF Time-Series Library, e.g., the common PPA openHistorian 1.0 instance running in an openPDC. You can also migrate existing openHistorian 1.0 .D data files into openHistorian 2.0 .D2 data files using the Archive Upgrade Utility that comes installed with the openHistorian.

To start using the openHistorian 2.0 within an existing GSF Time-Series Library based application, begin by following these steps.

Known Issues

The built-in System Status dashboard "Active Input Connections" single-stat panel reports an invalid value for system with multiple direct connections or GEP based inputs, change the metric query to the following to produce a correct count:

SliceCount(10, Exclude(0, 0, FILTER ActiveMeasurements WHERE PointTag LIKE '%!PMU:ST4'))

To change the query you may need to first make the page “editable”. To do so, click the “gear” icon at the top of the page and select “Make Editable”, save the dashboard, then refresh the page. Now when you click on the panel titled “Active Input Connections” you can click “Edit” and paste in the corrected metric query above.

This release has been updated, note the following changes since v2.4.22:

  • Fixed references for TrendMeasurements view to correct zoom out and pan
  • Updated Grafana deployment to 4.6.3
  • Reduced web file deployment footprint

openHistorian v2.2

Note: This is not the latest version.

Official stable release of version 2.2 of the openHistorian (v2.2.25).

See full change log since last release.

New Features and Improvements

  • GrafanaAdapters: Added full set of aggregation and operational functions that operate on a per-series or per-set for all data sources that implement Grafana interfaces. See documentation.
  • LogFileViewer: Added new enhanced general logging capabilities along with a new application, Log File Viewer, that is used to analyze logs.
  • Web UI: Updated home page to include time displays in both UTC and local time.
  • GSF.TimeSeries: Added up-time statistics for system, subscriber, publisher, input streams and output streams.
  • GSF.TimeSeries: Added a new enhanced version of the time-series special compression algorithm, automatically enabled for new connections, used with the Gateway Exchange Protocol that uses much less bandwidth. Add ; compression=true to connection string of existing GEP subscriptions to enable.
  • GSF.TimeSeries: Created a lookup cache for the main adapter meta-data using dictionary based lookups. This improved load times for input adapters on large systems (e.g., from 160 seconds to less than 1 second in some cases).
  • GSF.TimeSeries: Updated measurement definitions to carry meta-data as part of measurement key with an internal reference inside measurement implementations to reduce total memory footprint requirements for new measurements.
  • GSF.Core: Added a static timer class to allow many hundreds of scheduled events that run at the same interval to be associated with a single wait event instead of creating a new timer for each event (e.g., as hundreds of devices needing to check statistics every second) - this alleviates thread pool exhaustion that can occur when hundreds of timer events get executed at the same time.

Important Fixes

  • GSF.SortedTreeStore: Fixed bug in UnionTreeStreamSortHelper (found by @yuwenpeng) that could cause occasional data loss when duplicate records were being written to the openHistorian - in cases of encountered duplicates (i.e., by key of time and ID), there was a possibility that the duplicate record could cause a rollover operation to end prematurely.
  • DataSubscriber: Updated measurements received with GEP to apply any linear adjustments defined in the local configuration.
  • GSF.Core: Added code to ensure that log files won't become deadlocked if an error occurs during rollover.
  • GSF.TimeSeries: Updated DataSubscriber meta-data synchronization to exclude calculation and alarm signals from the device measurement removal processing such that if a local subscription creates new calculations associated with a subscribed device, the locally created measurements will not get automatically removed at the next synchronization.
