Dotaz: HotSaNIC - ping nevytváří obrázky

[topenar]

Nevím si rady s modulem ping. Všechny ostatní moduly běží bez problému, ale ping nevytváří obrázky. Proces pingu běží, ale skript pro vytváření nic neudělá.

Mám naistalováno: Linux version 2.6.18-1.2257.fc5 (brewbuilder@hs20-bc1-5.build.redhat.com) (gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)) #1 Fri Dec 15 16:04:33 EST 2006

Hotsanic 0.5.0-pre5

RRDtool 1.2.15

"Chyba" při spuštění skriptu diagrams.pl:

----- modules/ping ----- 
creating images for 10.33.10.67 ( AP Bratrk) ... 
Use of uninitialized value in printf at ./diagrams.pl line 167 (#1) 
(W uninitialized) An undefined value was used as if it were already 
defined. It was interpreted as a "" or a 0, but maybe it was a mistake. 
To suppress this warning assign a defined value to your variables. 

To help you figure out what was undefined, perl tells you what operation 
you used the undefined value in. Note, however, that perl optimizes your 
program and the operation displayed in the warning may not necessarily 
appear literally in your program. For example, "that $foo" is 
usually optimized into "that " . $foo, and the warning will refer to 
the concatenation (.) operator, even though there is no . in your 
program.

[themax]

co si matne pamatuju, tak se tam v konfiguraku nastavovalo jak to ma poustet ping, jestli ma pouzit nejakej perlovej modul nebo systemovej ping. ja mam dojem tam mel nastavenej systemovej ping achodi mi to. kdyztak se v nedeli ozvi na icq 37781136 nebo jabber the.max@jabber.sh.cvut.cz a neco vymyslime

[topenar]

Použil jsem všechny kombinace nastavení HotSaNICu a to:

SYSPING="0" a PROTOCOL="icmp" nebo "tcp
SYSPING="1" a PROTOCOL="icmp" nebo "tcp

výsledek je stejný = žádné vytvořené imgs.

[LiM]

rekl bych ze se nic neuklada do rrd a nebo jsou poskozene zkusil bych je vymazal, overit jestli neni ve fw zakazany ping at uz REJECT nebo DROP a pak se pokusit o nejaky debug pri SYSPING="0" a PROTOCOL="icmp"

grep DEBUG /usr/local/HotSaNIC/settings
DEBUGLEVEL="110"

grep DEBUG /usr/local/HotSaNIC/modules/ping/platform/default.pm
        if (defined($args{DEBUGLEVEL}) && $args{DEBUGLEVEL}>100) { print " > $host\n"; }
       if ($args{DEBUGLEVEL}>101) { printf " < %-15s (%3.2f/%3.2f/%3.2f)\n",$host,$min,$avg,$max; }

a pak uz jen koukat do logu v HotSaNIC/var/log/HotSaNIC.log

[topenar]

RRD DBs smazány, firewal byl a je vypnutý, settings nastaveno. V logu se objevuje stále stejná hláška:

Use of uninitialized value in printf at ./diagrams.pl line 167 (#1)
    (W uninitialized) An undefined value was used as if it were already
    defined.  It was interpreted as a "" or a 0, but maybe it was a mistake.

    you used the undefined value in.  Note, however, that perl optimizes your

    appear literally in your program.  For example, "that $foo" is
    usually optimized into "that " . $foo, and the warning will refer to

jeste pred generovanim grafu by se do logu mel davat debug pri samotnem sbirani dat viz

 grep DEBUG /usr/local/HotSaNIC/modules/ping/platform/default.pm
 if (defined($args{DEBUGLEVEL}) && $args{DEBUGLEVEL}>100) { print " > $host\n"; }
       if ($args{DEBUGLEVEL}>101) { printf " < %-15s (%3.2f/%3.2f/%3.2f)\n",$host,$min,$avg,$max; }

takze by tam mel byt host nebo IP a zatim sesbirane hodnoty

[topenar]

Podle logu se asi databáze plní.

Zdravím, právě teď jsem ten problém taky řešil, nainstaloval jsem Ubuntu, přetáhnul jsem tam Hotsanic se Slackwaru, kde fungoval skvěle, ale nevytvářely se obrázky k pingu a k pár dalším věcem. Chvilku jsem googlil a někdo doporučoval neinstalovat rrdtool jako balíček, ale zkompilovat si vlastní, to jsem udělal, ale pořád to nešlo, nakonec jsem nainstaloval perlovské moduly od nově zkompilovaného rrdtool (mimochodem verze 1.0.49) a všechno funguje jako na Slackovi:) Jen pro upřesnění, ten příkaz na nainstalování perlovských modulů je

make site-perl-install

Přeju hodně zdaru.

[topenar]

Díky za řešení. Downgrade na 1.0.49 + make site-perl-install zabral.

[LiM]

tak jeste je mozne zkusit tento patch http://charon.hkfree.org/wiki/index.php/Monitorov%C3%A1n%C3%AD_serveru#ping

[FATE]

tak jeste je mozne zkusit tento patch http://charon.hkfree.org/wiki/index.php/Monitorov%C3%A1n%C3%AD_serveru#ping

-ten odkaz nefunguje, je tu neco aktualnejsiho? FATE

[FATE]

ten link uz jede, asi nejakej problem u nich a ta zmena v $hotsanic/modules/ping/diagrams.pl pomoci vim editoru a zadanim :%s/n:",$/n",/gc - FUNGUJE TO

FATE

[pesi]

na patch se vykasli... staci manualne upravit soubor "diagram.pl" v radkach, ktere konci "n:" -> "n"

petrs

[Mr.Yoda]

Přesně tak, funguje to!.
Díky moc, chlape!

[pesi]

Problem je v tom, ze pouzivas novou verzi rrdtool ale "diagram.pl" je z predchozi verze. Staci nahradit vsechny konce radku, ktere konci "n:" za "n", tj. bez dvojtecky a melo by to jet.Aspon me to zabralo

Je to popsano v README HotSaNICu. petrs
