## 24.5 Traffic Charts

In the Status → Traffic Charts section you can view (in graphical format) the number of connections to individual services of Kerio MailServer and the number of processed messages (both incoming and outgoing) for a given period.

Figure 24.6. Traffic Charts

The graph allows the following parameter settings:

Monitored parameter

  Use the first field to choose the monitored parameter:

  - Connections / HTTP — the number of connections to the HTTP service

  - Connections/IMAP — the number of connections to the IMAP service

  - Connections / LDAP — the number of connections to the LDAP service

  - Connections / NNTP — the number of connections to the NNTP service

  - Connections / Outgoing SMTP — the number of outgoing connections of the SMTP service

  - Connections / Rejected SMTP — number of rejected connections to the SMTP service (connections blocked by the Spammer repellent filter)

  - Connections/POP3 — the number of connections to the POP3 service

  - Connections/SMTP — the number of connections to the SMTP service

  - Messages / Received — the number of messages processed by the MailServer (the total of outgoing and incoming SMTP messages and messages downloaded from remote POP3 mailboxes)

  - Messages / Spam — number of messages marked as spam by the antispam filter

Time range

  In the second field you can choose the time range you wish to monitor (the range can be from 2 hours to 30 days). The selected time range is always understood as the time until now (“last 2 hours”, “last 30 days”, etc.).

The legend below the graph shows the sampling interval (i.e. the time for which a sum of connections or messages is counted and is displayed in the graph).

Example: If 2 hours is selected as the time range the sampling frequency is 20 seconds. This means that a number of connections and/or messages is counted for the last 20 seconds and is written into the graph.

The following buttons are available below the graph:

  Y Axis

    Definition of the minimum and maximum values for the y axis.

    ### Note

    The scale of the x axis is determined by the time range that has been selected.

  Time

    This option defines which time type will be displayed in the chart (either the server time or the local time of the host the Kerio Administration Console is running on. The following rules are applied:

    - If Kerio Administration Console is run on the same host where Kerio MailServer is installed, both time types are equal.

    - The same rule is applied if the times on both hosts are synchronized (e.g. by the NTP protocol or in Windows NT domain).

    - If the times are not synchronized and both hosts are in the same time zone, we recommend to use the server time.

    - If the hosts are in different time zones, any of the two time types can be selected according to your needs.

  Show grid

    Grid can be showed or hidden in the graph.
