I've got a graph that shows in/out octets on a firewall interface. Whenever bandwidth gets above 300mb/s we start losing lines on the graph.
Running Zabbix 3.2.1 on CentOS 7:
Data is gathered from a SNMP LLD rule:
Name: SNMP Interface Discovery
Key: SNMP_IF_Discovery
SNMP OID: discovery[{#IFDESCR}, ifDescr, {#IFALIAS}, ifAlias, {#IFPHYSADDRESS}, ifPhysAddress, {#IFINOCTETS}, ifInOctets, {#IFOUTOCTETS}, ifOutOctets]
With two Item Prototypes:
Name: {$SITE.NAME} - Inbound Traffic on Interface {#IFALIAS} {#IFDESCR}
Key: ifInOctets[{#IFDESCR}]
SNMP OID: IF-MIB::ifInOctets.{#SNMPINDEX}
Type of information: Numeric (unsigned)
Data type: Decimal
Units: bps
Use custom multiplier: 8
Update interval (in sec): 60
History storage period (in days): 90
Trend storage period (in days): 1825
Store value: Delta (speed per second)
The strange thing is - when I'm viewing the graph in real time I will see the bar go along the screen and then when it refreshes again, it will suddenly have a gap in a place that used to have data. This will go on for a bit until it starts picking up data again.
When I view the custom graph, it shows the whole, and when I create a simple graph from the latest data on the interface, it shows the same hole in the data, so I think it might actually be losing data somehow?
