Reports And Monitoring
To help the platform administrators, CBRAIN has many reports in different locations, which are not readily visible to the user. This section describe all such reports. CBRAIN also has a comprehensive mechanism for tracking activity on the platform.
- Automatic tabular Report maker
- Tools report
- Data Provider reports
- Server reports
- Task statistics
- Portal log page
- Log information
The "Report maker" can generate many different kinds of reports in a tabular layout (e.g. reports about 'UserFile' or 'DataProvider'). This is a modular way to generate different reports.
To use the "Report maker":
- Go to "My Account" tab.
- Click on "Report Maker".
- Select "Report type" in the gray box. Most reports count the number of objects that are accessible, but some of them perform summation of some attributes.
- Click "Lookup columns and rows" and the form is adjusted to show which attributes can be selected for the rows and columns of the table.
- Select an attribute for the rows and columns using each of the selection boxes shown at the top and left of the table area.
- Click "Generate report" and a table is created with hot links to the appropriate index pages for the objects. You can modify the report's properties and regenerate it at any time.
- Optional filters can be added in order to refine the report.
"Access reports" generates reports about the tools.
To use "Access reports":
- Go to the "Tools" tab.
- Click "Access reports".
- On this page quick links or a more specific combination can be used to show
the following reports:
- By execution server: The first line of this report lists all of the tools not configured for the server. After that, there is a table with a list of tools and versions configured for the server. There is also information about the project associated with each tool and a list of users that do not have access to the tools.
- By tool: The first line of this report lists all the execution servers where the tools are not configured. After that, there is a table with a list of tools and versions configured for the server, information about the project associated with each tool and a list of users that do not have access to the tools.
-
By user: If user is selected there are four different reports:
- Member of editable projects: A table showing all the groups a user belongs to.
- Execution servers access: A table showing execution servers accessible by the user.
- Tool access summary: A table showing the number of tool versions accessible per server by the user.
- Tool versions access details: A very comprehensive table showing the list of tools and tool versions by execution server with the associated projects and a column showing tool versions accessible by the user. This table is ideal for determining why a user cannot get access to a particular tool.
- Custom report: A custom report can be created by selecting a particular execution server and/or a particular tool and/or a particular user.
There is an "Access?" link on the index page, on the right of the table, which can be clicked to find a link for a tool. Clicking on this latter link will redirect to the "Access Reports" by tool.
To show "User access reports":
- Go to the "Data Provider" tab.
- Click "User Access Report".
This table has rows for users and columns for Data Providers. Each cell of the table is a green circle when the user has access to the Data Provider or a red cross otherwise.
To show the "Transfer restrictions" report:
- Go to the "Data Provider" tab.
- Click "Transfer Restrictions Report".
This table shows which file transfers are allowed between Data Providers. Each cell of the table has two symbols, where a green circle means allowed and red cross means not allowed. Transfers are possible if both symbols are green circle/green circle.
-
First symbol: This table shows restrictions for transferring files between Data Provider pairs, independently of the states of any other resources. The restrictions are not necessarily symmetrical: it is possible to configure Data Providers A and B such that transfers from A → B are allowed (green circle) while transfers from B → A are not (red cross).
-
Second symbol: Since transfers are performed by the CBRAIN Portal, there are three other factors to take into account:
- Whether or not Data Providers are online or offline;
- Whether or not Data Providers are read/write or read only;
- Whether or not the current Portal itself has access to each Data Provider.
In such cases, Data Providers will be annotated with "offline", "read only" and/or "portal has no access". If all three properties allow the file transfers, the second symbol will be a green circle; it will be a red cross otherwise.
To show the "Disk usage report":
- Go to the "Data Provider" tab.
- Click "Disk Usage Report".
This is a custom report with rows for users and columns for Data Providers. Each cell contains the size of the data by user and by Data Provider, and a hot link is shown with the "Number entries/Number files". Follow the hot link to be redirected to the Files index page with filters to show only the particular entries that are requested. In each cell there is a color coded chip to represent the size of the data, from blue to red.
To show the "User Access Reports":
- Go to the "Servers" tab.
- Click "User Access Report".
This is a simple table with rows for users and columns for servers. Each cell in the table is a green circle when the user has access to the Data Provider or a red cross otherwise.
To show the "Disk Cache Report":
- Go to the "Servers" tab.
- Click "Disk Cache Report".
This page displays the size of the cache directory by user and server. The size of the data is color coded from blue to red. If the user has an active task on a particular server, a red message appears in the cell to inform the administrator. A filter can be added to select results by date. Cleanup of the cache can also be performed on this page.
To show the "Task Workdir Size report":
- Go to the "Servers" tab.
- Click "Task Workdir Size Report".
This is a custom report with rows for users and columns for servers. Each cell contains the size of the data by user and server, with a hot link with the "Number of tasks". Follow this hot link to be redirected to the Tasks index page, where filters can be used to select particular entries. In each cell there is a color coded chip to represent the size of the data, from blue to red.
To show the "Access to Data Providers" report:
- Go to the "Servers" tab.
- Click "Access to Data Providers".
This page shows which servers (rows) can access which Data Providers (columns). Each cell in the report can show:
- Green circle (access is allowed)
- Red cross
- Red cross and "no access"
- Green circle and "no access"
- Question marks, with or without "no access"
The report page can be consulted for further information on each of these options.
"No access" means that within CBRAIN the admin disallowed the connection, so servers cannot access files on the Data Provider at all, neither streaming nor synchronized, even if the Data Provider seems alive. Number 2 and 3 are slightly different, since the red cross means that the transfer is supposedly allowed, but when a test is made it still fails for reasons outside of CBRAIN's control (e.g. firewall rules).
To launch tasks on a particular execution server, they should be configured to access files on Data Providers marked by green circles.
If a Data Provider is identified as "not syncable" (below their name), its files can still be accessed through streaming APIs, but can never be fully synchronized on any server.
To show the "Task Statistics By Status" report
- Go to the "Servers" tab.
- Select a particular execution server for which you want to show statistics.
- Click "Task Statistics By Status".
This is a custom report with rows for users and columns for number of tasks with a particular status. The table only shows information for the particular execution server that you selected. Every cell contains a hot link; if you click on it you are redirected to the Tasks tab, listing all of the tasks with a particular status and user on the execution server.
To show the "Task Statistics By Type" report
- Go to the "Servers" tab.
- Select a particular execution server for which you want to show statistics.
- Click on "Task Statistics By Type".
This is a custom report with rows for users and columns for the number of tasks of a particular type. It only shows the information for the particular execution server you selected. Every cell contain a hot link; if you click on it you are redirected to the Tasks tab, listing all the tasks of a particular type, for the user and execution server you selected.
To use the "Portal log page":
- Go to the "Dashboard"
- Click "View logs"
This page shows the log information received by the portal. There is an option to use a filter, for example to only show the logs for a particular user, or to hide some lines and only show what is most relevant.
On each show page there is a "File info" section, where all of the changes that have affected the object are shown. In this way an administrator can track every change that happen for this entry in CBRAIN.
