You can upload decryption keys to browse encrypted logspaces for the duration of the session only. These keys are automatically deleted when you log out from syslog-ng Store Box(SSB).
To use session-only decryption keys
-
Select User menu > Private keystore. A pop-up window is displayed.
-
Select Temporary > 
, then select Certificate > 
. A pop-up window is displayed.

-
Paste or upload the certificate used to encrypt the logstore.
-
Select Key > . A pop-up window is displayed.
-
Paste or upload the private key of the certificate used to encrypt the logstore.
-
Repeat Steps 2-5 to upload additional keys if needed.

Click Apply.
You can add a private key (or set of keys) to a logstore, and use these keys to decrypt the logstore files. This way, anyone who has the right to search a particular logspace can search the messages. These decryption keys are stored unencrypted in the syslog-ng Store Box(SSB) configuration file.
As this may raise security concerns, avoid this solution unless absolutely necessary.
To assign decryption keys to a logstore
-
Navigate to Log > Logspaces and select the encrypted logspace you want to make searchable for every user via the SSB web interface.
-
Select Decryption private keys > . A pop-up window is displayed.

-
Paste or upload the private key of the certificate used to encrypt the logstore.
-
Repeat Steps 2-3 to upload additional keys if needed.
An additional key is needed when the certificate used to encrypt a logstore expires. When this happens, you have to upload a new certificate. However, to be able to read the logstore encrypted with the old (expired) certificate(s), you need to keep the old encryption key(s) with the new one.

The syslog-ng Store Box(SSB) appliance can create statistics from the Facility, Priority, Program, Pid, Host, Tags, and .classifier.class columns. Use Customize columns to add the required column, if necessary.
You can display statistics on the web interface, export the related data as CSV, and also save the statistics to include in a report.
To display statistics about the log messages, click the 
icon in the appropriate header of the table.
You can choose from Bar chart or Pie chart & List.
NOTE: For performance reasons, when creating statistics for a Multiple Logspace (see "Creating multiple logspaces" in the Administration Guide), syslog-ng Store Box(SSB) does not create statistics if the data upon which the statistics is based (for example, the hostname) has over 1000 entries in any of the member logspaces. In this case, SSB displays the Number of member statistics has too many entries error message.
Figure 200: Search > Logspaces — Displaying log statistics as Bar chart
In Pie chart & List view, percentages add up to 100%. The only exception to this is when statistics are based on Tags. Since statistics are provided for tags rather than messages, when messages have multiple tags, the percentages may add up to more than 100%.
Figure 201: Search > Logspaces — Displaying log statistics as Pie chart & List
Statistics will show the item with the largest number of entries first. To display the item with the least number of entries first, select Least.
NOTE: When navigating to the "future" in the search bar, it is possible that the number of logs displayed in the Search results differs from the number of logs displayed in the Count part of the Host pie chart.
To avoid this, do not navigate to the "future".
If this has already happened, save the search expression that you have used somewhere, and then refresh the page by clicking Log > Search again. Note that it will display the original state of the Search page, meaning that for example it will remove all search expressions that you have entered before.
You can export these statistics in CSV format using the Export all to CSV option, or you can include them in reports as a subchapter.
