Clamdtop(1) Clam AntiVirus Clamdtop(1)
NAME
clamdtop - monitor the Clam AntiVirus Daemon
SYNOPSIS
clamdtop [options] [clamdspec ...]
DESCRIPTION
clamdtop is a tool to monitor one or multiple clamd(s). It has a
(color) ncurses interface, that shows the jobs in clamd's queue, memory
usage, and information about the loaded signature database. You can
specify on the command-line to which clamd(s) it should connect to. By
default it will attempt to connect to the local clamd as defined in
clamd.conf.
OPTIONS
-h, --help
Display help information and exit.
-V, --version
Print version number and exit.
--config-file=FILE
Read clamd settings from FILE, to determine how to connect to
it.
clamdspec
Specifies the clamd to connect to: either a path to the local
(unix domain) socket of clamd, or an IP address and an port num-
ber (that defaults to 3310) to connect to a local or remote
clamd using TCP/IP.
OVERVIEW
KEYS:
H
Displays a short helpscreen, describing the meaning of various
elements on the display.
Q
Quits clamdtop
R
Resets the maximum values.
up arrow, down arrow
If you are monitoring multiple clamds then clamdtop will show an
overview screen by default. You can use the up arrow and down
arrow keys to cycle through each clamd individually, and the
overview screen. A blue bar will highlight the clamd that is
currently shown in detail. On the overview screen none of the
clamds is selected (hence no blue bar), and you can see the
items from the queue of all clamds.
The top bar
Shows the version of clamdtop and the current time. Clamdtop updates
the display once every 2 seconds.
The list of clamds
Shows the clamds that clamdtop is connected to, and statistics about
them.
NO Unique clamd number
CONNTIME
How long clamdtop has been connected (reset upon a reconnect)
LIV Total number of live threads
IDL Total number of idle threads
QUEUE Number of items in queue
MAXQ Maximum number of items observed in the queue
MEM Total memory usage (if available)
HOST Which clamd, local means unix socket
ENGINE Engine version

DBTIME Database publish time
Clamd detailed view
Primary threads live

Primary threads idle
The number of threads that are idle, waiting for commands. They
will exit after IdleTimeout (30 seconds).
Primary threads max
The maximum number of threads configured.
Queue items
The number of items (scanjobs) in clamd's queue that are waiting
for a free thread to be processed.
Queue max
The maximum number of items observed in clamd's queue.
The memory usage view
If available, it will show details on clamd's memory usage:
Mem heap
The amount of memory used by libc from the heap in MegaBytes.
Mem mmap
The amount of memory used by libc from mmap-allocated memory in
MegaBytes.
Mem unused
The amount of memory that can be reclaimed by libc.
Libc used
The amount of useful memory allocated by libc.
Libc free
The amount of memory allocated by libc, that can't be freed due
to fragmentation.
Libc total
The amount of memory allocated by libc from the system in total.
Pool count
The number of mmap regions allocated by clamd' memory pool allo-
cator (for the signature database).
Pool used
The amount of memory used by clamd's memory pool allocator (for
the signature database).
Total The total amount of memory allocated by clamd's memory pool al-
locator.
The clamd job queue
COMMAND
Kind of command being executed, STATS is clamdtop, SCAN/CON-
TSCAN/FILDES/MULTISCAN is scan of a file/directory, MULTISCAN-
FILE is scan of one item by a MULTISCAN job.
QUEUEDSINCE
The time since the command got queued, until now.
FILE The name of the file being processed (if applicable).
EXAMPLES
(1) To connect to the clamd configured in the default clamd.conf:
clamdtop
(2) To connect to the clamd configured in another clamd.conf:
clamdtop --config-file=/path/to/clamd.conf
(3) To connect to a clamd running on another machine (192.168.0.3) on
the LAN:
clamdtop 192.168.0.3
(4) To connect to a clamd running on another machine (192.168.0.3) on a
non-default port (3410):
clamdtop 192.168.0.3:3410
(5) To monitor the local clamd and 2 other remote clamds over TCP/IP:
clamdtop localhost 192.168.0.3 192.168.0.4
NOTES
clamdtop uses colors if the terminal is capable of colors. If you know
your terminal is capable of colors, yet you aren't seeing any, then
check that your TERM environment variable is set correctly. For exam-
ple try setting it to TERM=xterm-color if you are in an xterm-like en-
vironment. IPv6 support has been added. If specifying an IPv6 address,
please use the normal IPv6 addressing rules. If specifying both an IPv6
address and a port combination, encapsulate the IPv6 address in square
brackets (e.g. [::1]:3410).
RETURN CODES
0 : Normal termination
>0: Error occurred.
