Maintenance: The remaining days of validity of the maintenance support.
Support access: Whether the support team can access the IFA 3610/IFA 2610/IFA 1610 appliances or not. In the former
case, it also shows the date until the access is granted.
This plugin also shows the remaining days of validity of the additional modules Panda Antivirus and Commtouch, if
purchased.
1.1.2 Hardware Information Plugin
It shows the main hardware information of the appliance and the resource availability. All the information are provided
with the absolute value (graphically with a small bar and in number at the end of a line) and the percentage of their use.
The only exception is the CPU load, which shows only the percentage of use, in graphic and numbers.
CPU x: The load of the CPU, where x represents the CPU number, for those appliance that have more than one CPU.
Memory: The amount of the RAM memory used.
Swap: How much swap disk space is used. A high percentage here usually means there is something not working
correctly.
Main disk: The usage of the root partition.
Temp: The space used in the /tmp partition.
Data disk: the usage of the /var partition.
Configuration disk: The space occupied by the partition containing all the services and settings of the IFA 3610/IFA
2610/IFA 1610 appliances.
Log disk: The amount of space used in the partition containing the logs.
The latter values, showing disk space availability, can vary depending on the appliance, since the data, system, and log
partitions may be located in different places.
Warning: A partition on the hard disk (e.g., main disk, data disk, /var/log) shall never have a usage of 95% or more, as
this can cause malfunctioning and data loss.
1.1.3 Service Information Plugin
Information about the most important services installed on the IFA 3610/IFA 2610/IFA 1610 appliances, along with their
actual status, are displayed by this plugin. For each service is shown the status, either ON or OFF, and a summary of the
tasks accomplished during the last hour and the last days. A click on the service’s name expands or collapses additional
information on the tasks carried out by the service. For running services, there is the possibility to open in a new window
the respective Live Logs. Hence, if some number in the summaries sounds strange (e.g., a number of email rejected that
is twice as normal) or not common compared to the normal activities (e.g., the IDS has detected some attack), the logs
can be controlled to search for some useful message that has been recorded. The services currently supported by this
plugin are:
Intrusion Detection: The number of attacks logged by snort.
SMTP Proxy: Statistics about the e-mails processed. The number of e-mail currently in the postfix-queue, of the
received e-mails and how many of them were clean, the number of viruses found, and how many e-mails were
blocked.
HTTP Proxy: The numbers of cache misses and hits of squid and of the viruses found.
POP3 Proxy: Statistics about the received, blocked, and virus-containing e-mails that went through the POP3 Proxy.
Hint: Inactive services are marked with a red OFF message.
