NAME

clamdtop - monitor the Clam AntiVirus Daemon

CONTENTS

     The top bar
     The list of clamds
     Clamd detailed view
     The memory usage view
     The clamd job queue

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 number (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
DBVER Database version
DBTIME Database publish time

    Clamd detailed view

Primary threads live
  The number of threads that are executing commands or scanning.
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 allocator (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 allocator.

    The clamd job queue

COMMAND
  Kind of command being executed, STATS is clamdtop, SCAN/CONTSCAN/FILDES/MULTISCAN is scan of a file/directory, MULTISCANFILE 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 example try setting it to TERM=xterm-color if you are in an xterm-like environment. 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 brakets (e.g. [::1]:3410).

RETURN CODES

0 : Normal terminator
>0: Error occured.
