CountDuplicateCookies()

int org.openkilda.pce.janitor.FlowJanitor.CountDuplicateCookies

(

)

Returns

the number of cookies that have more than one flow. This shouldn't happen, but this is here to catch scenarios where it does. '2' means two cookies have more than 1 flow each.

Definition at line 93 of file FlowJanitor.java.

FlowsWithDuplicateCookies()

List<String> org.openkilda.pce.janitor.FlowJanitor.FlowsWithDuplicateCookies

(

boolean

verbose

)

Returns

the number of cookies that have more than one flow. This shouldn't happen, but this is here to catch scenarios where it does. '2' means two cookies have more than 1 flow each.

DELETE_DUPLICATE_FLOW

final String org.openkilda.pce.janitor.FlowJanitor.DELETE_DUPLICATE_FLOW

static

Initial value:

=
            "MATCH (:switch) -[rel:flow]-> (:switch)"+
                    " WHERE rel.flowid = %s AND rel.cookie = %d"+
                    " DELETE rel"

Use to delete a flow (ie in conjunction with DUPLICATE_FLOWS_QUERY)

DUPLICATE_COOKIES_QUERY

final String org.openkilda.pce.janitor.FlowJanitor.DUPLICATE_COOKIES_QUERY

static

Initial value:

=
                    "MATCH (:switch) -[rel:flow]-> (:switch)" +
                            " WITH rel.cookie as affected_cookie, COUNT(rel.cookie) as cookie_num" +
                            " WHERE cookie_num > 1" +
                            " MATCH (:switch) -[rel2:flow]-> (:switch)" +
                            " WHERE rel2.cookie = affected_cookie" +
                            " RETURN affected_cookie, rel2.flowid as affected_flow_id" +
                            " ORDER BY affected_cookie "

Use to get the flows that share the same cookie (eg 1 cookie, N flows)

DUPLICATE_FLOWS_QUERY

final String org.openkilda.pce.janitor.FlowJanitor.DUPLICATE_FLOWS_QUERY

static

Initial value:

=
            "MATCH (:switch) -[rel:flow]-> (:switch)"+
                    " WITH rel.flowid as affected_flow_id, COUNT(rel.flowid) as flow_num"+
                    " WHERE flow_num > 2"+
                    " MATCH (:switch) -[rel2:flow]-> (:switch)"+
                    " WHERE rel2.flowid = affected_flow_id"+
                    " RETURN affected_flow_id, rel2.cookie as affected_flow_cookie" +
                    " ORDER BY affected_flow_id"

Use to get the flows that have multiple instances (ie N flows .. should be just 1 flow)

DUPLICATE_VLAN_QUERY

final String org.openkilda.pce.janitor.FlowJanitor.DUPLICATE_VLAN_QUERY

static

Initial value:

=
            "MATCH (:switch) -[rel:flow]-> (:switch)" +
                    " WITH rel.transit_vlan as affected_cookie, COUNT(rel.transit_vlan) as cookie_num" +
                    " WHERE cookie_num > 1" +
                    " MATCH (:switch) -[rel2:flow]-> (:switch)" +
                    " WHERE rel2.transit_vlan = affected_cookie and rel2.transit_vlan > 0" +
                    " RETURN affected_cookie, rel.transit_vlan AS transit_vlan, rel2.flowid as affected_flow_id" +
                    " ORDER BY affected_cookie"

Use to get the flows that share the same transit vlan (eg 1 t-vlan, N flows)
