Nagios check memory plugin

Why doesn't Nagios have a check_memory as part of the initial set of plugins that come by def开发者_StackOverflow中文版ault? Like check_http, check_load etc?

Thanks!

According to Nagios Plugins the plugins in that project need to meet certain criteria, here is a statement from the FAQ:

There are two types of plugins included in the distribution:

• Plugins that are officially maintained by the nagios plugin developer team
• Plugins that are distributed in the contrib directory

Sooner or later all the contrib plugins should be hosted at the official 3rd Party Nagios plugin page Nagios Exchange

Contrib plugins have to be installed manually. They are not affected by the build process.

Here is a list of the actively maintained Plugins:

check_apt, check_breeze, check_by_ssh, check_clamd, check_cluster, check_dhcp, check_dig, check_disk, check_disk_smb, check_dns, check_dummy, check_file_age, check_flexlm, check_fping, check_ftp, check_game, check_hpjd, check_http, check_icmp, check_ide_smart, check_ifoperstatus, check_ifstatus, check_imap, check_ircd, check_jabber, check_ldap, check_load, check_log, check_mailq, check_mrtg, check_mrtgtraf, check_mssql, check_mysql, check_mysql_query, check_nagios, check_netdns, check_nntp, check_nntps, check_nt, check_ntp_peer, check_ntp_time, check_nwstat, check_oracle, check_overcr, check_pgsql, check_ping, check_pop, check_procs, check_radius, check_real, check_rpc, check_sensors, check_simap, check_smtp, check_snmp, check_spop, check_ssh, check_ssmtp, check_swap, check_tcp, check_time, check_udp, check_ups, check_users, check_wave

And these plugins are currently distributed in the contrib directory:

check_adptraid, check_apache, check_apc_ups, check_appletalk, check_arping, check_asterisk, check_axis, check_backup, check_bgpstate, check_breeze, check_cluster, check_cluster2, check_compaq_insight, check_cpqarray, check_digitemp, check_dlswcircuit, check_dns_random, check_email_loop, check_fan_cpq_present, check_fan_fsc_present, check_flexlm, check_frontpage, check_hltherm, check_hprsc, check_http-with-client-certificate, check_hw, check_ica_master_browser, check_ica_metaframe_pub_apps, check_ica_program_neigbourhood, check_inodes, check_inodes-freebsd, check_ipxping, check_javaproc, check_joy, check_linux_raid, check_lmmon, check_log2, check_lotus, check_maxchannels, check_maxwanstate, check_mem, check_ms_spooler, check_mssql, check_nagios, check_nagios_db, check_nagios_db_pg, check_netapp, check_nmap, check_oracle_instance, check_oracle_tbs, check_ora_table_space, check_pcpmetric, check_pfstate, check_qmailq, check_rbl, check_remote_nagios_status, check_rrd_data, check_sap, check_smart, check_smb, check_snmp_disk_monitor, check_snmp_printer, check_snmp_process_monitor, check_snmp_procs, check_sockets, check_temp_cpq, check_temp_fsc, check_timeout, check_traceroute, check_traceroute-pure_perl, check_uptime, check_vcs, check_wave, check_wins

As you can see there isn't an official check_memory plugin included in the maintained plugins, however you can find plugins that do support what you are looking for on Naigos Exchange.

if you install nagios-snmp-plugins from http://nagios.manubulon.com/ then you should have check_snmp_mem.pl and that will do the memory monitoring
