Nagios  nsca插件进程突然死掉

---

nsca监控属于被动式监控，是nagios的一个重要插件；使用克隆的方式增加nagios分布式节点一段时间后，nsca进程自动关闭

原因：nsca配置文件没有修改

[root@sznagiosapp1 etc]# cat nsca.cfg

# Sample NSCA Daemon Config File

####################################################

# LOG FACILITY
# The syslog facility that should be used for logging purposes.

log_facility=daemon

# Check Result directory.  If passed, skip command pipe and submit
# directly into the checkresult directory.  Requires Nagios 3+
# For best results, mount dir on ramdisk.

#check_result_path=/usr/local/nagios/var/checkresults

# PID FILE
# The name of the file in which the NSCA daemon should write it's process ID
# number.  The file is only written if the NSCA daemon is started by the root
# user as a single- or multi-process daemon.

pid_file=/var/run/nsca.pid

# PORT NUMBER
# Port number we should wait for connections on.
# This must be a non-priveledged port (i.e. > 1024).

server_port=5667

# SERVER ADDRESS
# Address that NSCA has to bind to in case there are
# more as one interface and we do not want NSCA to bind
# (thus listen) on all interfaces.

server_address=192.168.9.122  （服务器ip对应）

# NSCA USER
# This determines the effective user that the NSCA daemon should run as.  
# You can either supply a username or a UID.
#
# NOTE: This option is ignored if NSCA is running under either inetd or xinetd

nsca_user=nagios

# NSCA GROUP
# This determines the effective group that the NSCA daemon should run as.  
# You can either supply a group name or a GID.
#
# NOTE: This option is ignored if NSCA is running under either inetd or xinetd

nsca_group=nagios

# NSCA CHROOT
# If specified, determines a directory into which the nsca daemon
# will perform a chroot(2) operation before dropping its privileges.
# for the security conscious this can add a layer of protection in
# the event that the nagios daemon is compromised.  
#
# NOTE: if you specify this option, the command file will be opened
#       relative to this directory.

#nsca_chroot=/var/run/nagios/rw

# DEBUGGING OPTION
# This option determines whether or not debugging
# messages are logged to the syslog facility.
# Values: 0 = debugging off, 1 = debugging on

debug=0

# COMMAND FILE
# This is the location of the Nagios command file that the daemon
# should write all service check results that it receives.

command_file=/usr/local/nagios/var/rw/nagios.cmd

# ALTERNATE DUMP FILE
# This is used to specify an alternate file the daemon should
# write service check results to in the event the command file
# does not exist.  It is important to note that the command file
# is implemented as a named pipe and only exists when Nagios is
# running.  You may want to modify the startup script for Nagios
# to dump the contents of this file into the command file after
# it starts Nagios.  Or you may simply choose to ignore any
# check results received while Nagios was not running...

alternate_dump_file=/usr/local/nagios/var/rw/nsca.dump

# AGGREGATED WRITES OPTION
# This option determines whether or not the nsca daemon will
# aggregate writes to the external command file for client
# connections that contain multiple check results.  If you
# are queueing service check results on remote hosts and
# sending them to the nsca daemon in bulk, you will probably
# want to enable bulk writes, as this will be a bit more
# efficient.
# Values: 0 = do not aggregate writes, 1 = aggregate writes

aggregate_writes=0

# APPEND TO FILE OPTION
# This option determines whether or not the nsca daemon will
# will open the external command file for writing or appending.
# This option should almost *always* be set to 0!
# Values: 0 = open file for writing, 1 = open file for appending

append_to_file=0

# MAX PACKET AGE OPTION
# This option is used by the nsca daemon to determine when client
# data is too old to be valid.  Keeping this value as small as
# possible is recommended, as it helps prevent the possibility of
# "replay" attacks.  This value needs to be at least as long as
# the time it takes your clients to send their data to the server.
# Values are in seconds.  The max packet age cannot exceed 15
# minutes (900 seconds).  If this variable is set to zero (0), no
# packets will be rejected based on their age.

max_packet_age=60

# DECRYPTION PASSWORD
# This is the password/passphrase that should be used to descrypt the
# incoming packets.  Note that all clients must encrypt the packets
# they send using the same password!
# IMPORTANT: You don't want all the users on this system to be able
# to read the password you specify here, so make sure to set
# restrictive permissions on this config file!

password=password123

# DECRYPTION METHOD
# This option determines the method by which the nsca daemon will
# decrypt the packets it receives from the clients.  The decryption
# method you choose will be a balance between security and performance,
# as strong encryption methods consume more processor resources.
# You should evaluate your security needs when choosing a decryption
# method.
#
# Note: The decryption method you specify here must match the
#       encryption method the nsca clients use (as specified in
#       the send_nsca.cfg file)!!
# Values:
#
#       0 = None        (Do NOT use this option)
#       1 = Simple XOR  (No security, just obfuscation, but very fast)
#
#       2 = DES
#       3 = 3DES (Triple DES)
#       4 = CAST-128
#       5 = CAST-256
#       6 = xTEA
#       7 = 3WAY
#       8 = BLOWFISH
#       9 = TWOFISH
#       10 = LOKI97
#       11 = RC2
#       12 = ARCFOUR
#
#       14 = RIJNDAEL-128
#       15 = RIJNDAEL-192
#       16 = RIJNDAEL-256
#
#       19 = WAKE
#       20 = SERPENT
#
#       22 = ENIGMA (Unix crypt)
#       23 = GOST
#       24 = SAFER64
#       25 = SAFER128
#       26 = SAFER+
#

decryption_method=1
