Munin

Hálózatok egyéb

Sziasztok, a fenti temaban lenne szuksegem egy kis segitsegre,
a munin illetve munin-node ugyanazon a gepen va, le is fut szepen, a
html oldalak is ujrageneralodnak, a munin-cron nak koszonhetoen.
A doksit tegnap egesz nap bujtam illetve a guglit, de sajnos nem
gyartja le a grafikonokat, holott a munin-graph is szepen lefut,
a logban hibakat nem latok ! Apache beallitva !

Az rrdtools is fent van !

Van valkinek otlete ? koszi elore is

Szia

Ha minden OK akkor csak generál, de kérdés, hogy hova.

Erre mit mond: find / -name *day.png ?

Cs

/usr/share/pixmaps/gnome-day.png
/usr/share/icons/crystalsvg/22x22/actions/today.png
/usr/share/icons/crystalsvg/16x16/actions/today.png
/usr/share/icons/crystalsvg/32x32/actions/today.png
/usr/share/icons/gnome/24x24/stock/generic/stock_calendar-view-day.png

Az a baj, hogy le sem generalja a grafikonokat, de nem tudom miert :-(

Mire gondolsz ?

A munin.conf ban benne van és ua. mint a munin-node.conf ban !

## Then we want totals...

# # The graph "load1". We want to see the loads of both machines...

# load1.graph_title Loads side by side
# load1.graph_order fii=fii.foo.com:load.load fay=fay.foo.com:load.load

# # The graph "load2". Now we want them stacked on top of each other.

# load3.combined_loads.label Combined loads # Must be set, as this is
# # not a dummy field!
#
## ...and on a side note, I want them listen in another order (default is
## alphabetically)
#
# # Since [foo.com] would be interpreted as a host in the domain "com", we
# # specify that this is a domain by adding a semicolon.

Igazabol az zavar, hogy a logban semmi hasznalhato info, hogy miert nem gyartja le a kepeket.

Hát ez nem túl biztató:

2007/11/08-15:01:57 Couldn't chown "/var/run/munin/munin-node.pid" [A m%C5%B1velet nem engedett]

Ha nincs elfogaható PIDje a munin-node-nak az szerintem okozhat ilyen problémát.

A munin user ( akinek a nevében fut a munin-node ) tudja "irni olvasni futtatni/belépni" a /var/run/munin/ könyvtárat és annak tartalmát?

Meg szerintem konzol ne beszéljen magyarul.

Koszi, de megneztem mar, igen tud ott mindent csinalni, a tobbi *.pid a muninhoz ott is van !

A munin-node.pid letre sem jon !

( Elbandi v | 2007. 11. 08., cs – 21:47 )

lepj at munin userbe:
su -s /bin/bash - munin

aztan futtasd a progikat:
/usr/share/munin/munin-update --nofork --debug --stdout
/usr/share/munin/munin-graph --debug
/usr/share/munin/munin-html --debug

Elbandi
ui: ne rootkent futtast, mert akkor a letrehozott fajlok root jogaban leszek, amit majd nemtud felulirni a munin user.

--
A vegtelen ciklus is vegeter egyszer, csak kelloen eros hardver kell hozza!

Koszi, lefutattam, semmi hiba, de mint munin user nem fut akkor sem !
A fileok mind a munin tulajdonaban vannak 7 jogokkal !
Ill ami kell neki azt neztem, hogy azok is !

Persze nem szeretnem root kent futtatni !!!

Szia!

Végül megoldottad valahogy?

Gyakorlatilag ugyanez a gondom: hiba semmi, de rrd fájlok és graph nem kerül sehova.

Nos. Hajnali 4 óta én is ezzel harcolok. Sokat segítettek a fent írtak.
Hátha valakinek jól jön a tapasztalatom, mert mostan megyen :) :
munin írhat olvashat a 

/var/www/html/munin/

könyvtárban.
Igen ám, de a 

/var/www/html/

valamint a 

/var/www/

könyvtárak 750-os jogosultságúak a www-data usernek. Ergo: szép hogy a muniné a könyvtára, de ha nem engedjük eljutni odáig akkor b@#*hatjuk... :)

Nekem ez segített.

[szerk:] bocs, a megoldás lemaradt (csk a teljesség kedvéért): 


chmod 755 /var/www
chmod 755 /var/www/html
